Fix node package ci

in fact, `get_chat_msgs()` with `marker1before` is not used on iOS,

in an anyway complicated area and is probably not worth the effort.

+# Webxdc Developer Reference
+
+(This document may eventually be merged with the [webxdc guidebook](https://deltachat.github.io/webxdc_docs/), where you may currently find other useful information.)
+
+## Webxdc File Format
+
+- a **Webxdc** is a **ZIP-file** with the extension `.xdc`
+- the ZIP-file must use the default compression methods as of RFC 1950,
+  this is "Deflate" or "Store"
+- the ZIP-file must contain at least the file `index.html`
+- if the Webxdc is started, `index.html` is opened in a restricted webview
+  that allow accessing resources only from the ZIP-file
+
+
+## Webxdc API
+
+There are some additional APIs available once `webxdc.js` is included
+(the file will be provided by the concrete implementations,
+no need to add `webxdc.js` to your ZIP-file):
+
+```html
+<script src="webxdc.js"></script>
+```
+
+### sendUpdate()
+
+```js
+window.webxdc.sendUpdate(update, descr);
+```
+
+A Webxdc is usually shared in a chat and run independently on each peer.
+To get a shared state, the peers use `sendUpdate()` to send updates to each other.
+
+- `update`: an object with the following properties:  
+    - `update.payload`: any javascript primitive, array or object.
+    - `update.info`: optional, short, informational message that will be added to the chat,
+       eg. "Alice voted" or "Bob scored 123 in MyGame";
+       usually only one line of text is shown,
+       use this option sparingly to not spam the chat.
+    - `update.document`: optional, name of the document in edit,
+       must not be used eg. in games where the Webxdc does not create documents
+    - `update.summary`: optional, short text, shown beside Webxdc icon;
+       it is recommended to use some aggregated value,  eg. "8 votes", "Highscore: 123"
+
+- `descr`: short, human-readable description what this update is about.
+  this is shown eg. as a fallback text in an email program.
+
+All peers, including the sending one,
+will receive the update by the callback given to `setUpdateListener()`.
+
+There are situations where the user cannot send messages to a chat,
+eg. if the webxdc instance comes as a contact request or if the user has left a group.
+In these cases, you can still call `sendUpdate()`,
+however, the update won't be sent to other peers
+and you won't get the update by `setUpdateListener()`.
+
+
+### setUpdateListener()
+
+```js
+let promise = window.webxdc.setUpdateListener((update) => {}, serial);
+```
+
+With `setUpdateListener()` you define a callback that receives the updates
+sent by `sendUpdate()`. The callback is called for updates sent by you or other peers.
+The `serial` specifies the last serial that you know about (defaults to 0). 
+The returned promise resolves when the listener has processed all the update messages known at the time when  `setUpdateListener` was called. 
+
+Each `update` which is passed to the callback comes with the following properties: 
+
+- `update.payload`: equals the payload given to `sendUpdate()`
+
+- `update.serial`: the serial number of this update.
+  Serials are larger `0` and newer serials have higher numbers.
+  There may be gaps in the serials
+  and it is not guaranteed that the next serial is exactly incremented by one.
+
+- `update.max_serial`: the maximum serial currently known.
+  If `max_serial` equals `serial` this update is the last update (until new network messages arrive).
+
+- `update.info`: optional, short, informational message (see `sendUpdate()`)
+
+- `update.document`: optional, document name as set by the sender, (see `sendUpdate()`),
+  implementations show the document name eg. beside the app icon or in the title bar
+
+- `update.summary`: optional, short text, shown beside icon (see `sendUpdate()`)
+
+
+### selfAddr
+
+```js
+window.webxdc.selfAddr
+```
+
+Property with the peer's own address.
+This is esp. useful if you want to differ between different peers -
+just send the address along with the payload,
+and, if needed, compare the payload addresses against selfAddr() later on.
+
+
+### selfName
+
+```js
+window.webxdc.selfName
+```
+
+Property with the peer's own name.
+This is name chosen by the user in their settings,
+if there is nothing set, that defaults to the peer's address.
+
+
+## manifest.toml
+
+If the ZIP-file contains a `manifest.toml` in its root directory,
+some basic information are read and used from there.
+
+the `manifest.toml` has the following format
+
+```toml
+name = "My Name"
+source_code_url = "https://example.org/orga/repo"
+```
+
+- `name` - The name of the Webxdc.
+  If no name is set or if there is no manifest, the filename is used as the Webxdc name.
+
+- `source_code_url` - Optional URL where the source code of the Webxdc and maybe other information can be found.
+  UI may make the url accessible via a "Help" menu in the Webxdc window.
+
+
+## Webxdc Icon
+
+If the ZIP-root contains an `icon.png` or `icon.jpg`,
+these files are used as the icon for the Webxdc.
+The icon should be a square at reasonable width/height;
+round corners etc. will be added by the implementations as needed.
+If no icon is set, a default icon will be used.
+
+
+## Webxdc Examples
+
+The following example shows an input field and  every input is show on all peers.
+
+```html
+<!DOCTYPE html>
+<html>
+  <head>
+    <meta charset="utf-8"/>
+    <script src="webxdc.js"></script>
+  </head>
+  <body>
+    <input id="input" type="text"/>
+    <a href="" onclick="sendMsg(); return false;">Send</a>
+    <p id="output"></p>
+    <script>
+    
+      function sendMsg() {
+        msg = document.getElementById("input").value;
+        window.webxdc.sendUpdate({payload: msg}, 'Someone typed "'+msg+'".');
+      }
+    
+      function receiveUpdate(update) {
+        document.getElementById('output').innerHTML += update.payload + "<br>";
+      }
+    
+      window.webxdc.setUpdateListener(receiveUpdate, 0);
+    </script>
+  </body>
+</html>
+```
+
+[Webxdc Development Tool](https://github.com/deltachat/webxdc-dev)
+offers an **Webxdc Simulator** that can be used in many browsers without any installation needed.
+You can also use that repository as a template for your own Webxdc -
+just clone and start adapting things to your need.
+
+
+### Advanced Examples
+
+- [2048](https://github.com/adbenitez/2048.xdc)
+- [Draw](https://github.com/adbenitez/draw.xdc)
+- [Poll](https://github.com/r10s/webxdc-poll/)
+- [Tic Tac Toe](https://github.com/Simon-Laux/tictactoe.xdc)
+- Even more with [Topic #webxdc on Github](https://github.com/topics/webxdc) or in the [webxdc GitHub organization](https://github.com/webxdc)
+
+
+## Closing Remarks
+
+- older devices might not have the newest js features in their webview,
+  you may want to transpile your code down to an older js version eg. with https://babeljs.io
+- viewport and scaling features are implementation specific,
+  if you want to have an explicit behavior, you can add eg.
+  `<meta name="viewport" content="initial-scale=1; user-scalable=no">` to your Webxdc
+- the `<title>` tag should not be used and its content is usually not displayed;
+  instead, use the `name` property from `manifest.toml`
+- there are tons of ideas for enhancements of the API and the file format,
+  eg. in the future, we will may define icon- and manifest-files,
+  allow to aggregate the state or add metadata.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+[![JavaScript Style Guide](https://img.shields.io/badge/code_style-prettier-brightgreen.svg)](https://prettier.io)
+
+`deltachat-node` primarily aims to offer two things:
+
+- A high level JavaScript api with syntactic sugar
+- A low level c binding api around  [`deltachat-core-rust`](..)
+
+This code used to live at [`deltachat-node`](https://github.com/deltachat/deltachat-node)

+
+</details>
+
+## Install
+
+By default the installation will build try to use the bundled prebuilds in the
+npm package. If this fails it falls back to compile `../deltachat-core-rust` from
+this repository, using `scripts/rebuild-core.js`.
+
+To install from npm use:
+
+```
+npm install deltachat-node
+```
+
+## Dependencies
+
+- Nodejs >= `v16.0.0`
+- rustup (optional if you can't use the prebuilds)
+
+> On Windows, you may need to also install **Perl** to be able to compile deltachat-core.
+
+## Build from source
+
+If you want to build from source, make sure that you have `rustup` installed.
+You can either use `npm install deltachat-node --build-from-source` to force
+building from source or clone this repository and follow this steps:
+
+1. `git clone https://github.com/deltachat/deltachat-core-rust.git`
+2. `cd deltachat-core-rust`
+3. `npm i`
+4. `npm run build`
+
+> Our `package.json` file is located in the root directory of this repository,
+> not inside this folder. (We need this in order to include the rust source
+> code in the npm package.)
+
+### Use build-from-source in deltachat-desktop
+
+If you want to use the manually built node bindings in the desktop client (for
+example), you can follow these instructions:
+
+First clone the
+[deltachat-desktop](https://github.com/deltachat/deltachat-desktop) repository,
+e.g. with `git clone https://github.com/deltachat/deltachat-desktop`.
+
+Then you need to make sure that this directory is referenced correctly in
+deltachat-desktop's package.json. You need to change
+`deltachat-desktop/package.json` like this:
+
+```
+diff --git i/package.json w/package.json
+index 45893894..5154512c 100644
+--- i/package.json
++++ w/package.json
+@@ -83,7 +83,7 @@
+     "application-config": "^1.0.1",
+     "classnames": "^2.3.1",
+     "debounce": "^1.2.0",
+-    "deltachat-node": "1.79.3",
++    "deltachat-node": "file:../deltachat-core-rust/",
+     "emoji-js-clean": "^4.0.0",
+     "emoji-mart": "^3.0.1",
+     "emoji-regex": "^9.2.2",
+```
+
+Then, in the `deltachat-desktop` repository, run:
+
+1. `npm i`
+2. `npm run build`
+3. And `npm run start` to start the newly built client.
+
+### Workaround to build for x86_64 on Apple's M1
+
+deltachat doesn't support universal (fat) binaries (that contain builds for both cpu architectures) yet, until it does you can use the following workaround to get x86_64 builds:
+
+```
+$ fnm install 17 --arch x64
+$ fnm use 17
+$ node -p process.arch
+# result should be x64
+$ cd deltachat-core-rust && rustup target add x86_64-apple-darwin && cd -
+$ git apply patches/m1_build_use_x86_64.patch
+$ CARGO_BUILD_TARGET=x86_64-apple-darwin npm run build
+$ npm run test
+```
+
+(when using [fnm](https://github.com/Schniz/fnm) instead of nvm, you can select the architecture)
+If your node and electron are already build for arm64 you can also try bulding for arm:
+
+```
+$ fnm install 16 --arch arm64
+$ fnm use 16
+$ node -p process.arch
+# result should be arm64
+$ npm_config_arch=arm64 npm run build
+$ npm run test
+```
+
+## Usage
+
+```js
+const { Context } = require('deltachat-node')
+
+const opts = {
+  addr: '[email]',
+  mail_pw: '[password]',
+}
+
+const contact = '[email]'
+
+async function main() {
+  const dc = Context.open('./')
+  dc.on('ALL', console.log.bind(null, 'core |'))
+
+  try {
+    await dc.configure(opts)
+  } catch (err) {
+    console.error('Failed to configure because of: ', err)
+    dc.unref()
+    return
+  }
+
+  dc.startIO()
+  console.log('fully configured')
+
+  const contactId = dc.createContact('Test', contact)
+  const chatId = dc.createChatByContactId(contactId)
+  dc.sendMessage(chatId, 'Hi!')
+
+  console.log('sent message')
+
+  dc.once('DC_EVENT_SMTP_MESSAGE_SENT', async () => {
+    console.log('Message sent, shutting down...')
+    dc.stopIO()
+    console.log('stopped io')
+    dc.unref()
+  })
+}
+
+main()
+```
+this example can also be found in the examples folder [examples/send_message.js](./examples/send_message.js)
+
+### Generating Docs
+
+We are curently migrating to automaticaly generated documentation.
+You can find the old documentation at [old_docs](./old_docs).
+
+to generate the documentation, run:
+
+```
+npx typedoc
+```
+
+The resulting documentation can be found in the `docs/` folder.
+An online version can be found under [js.delta.chat](https://js.delta.chat).
+
+## Developing
+
+### Tests and Coverage
+
+Running `npm test` ends with showing a code coverage report, which is produced by [`nyc`](https://github.com/istanbuljs/nyc#readme).
+
+![test output](images/tests.png)
+
+The coverage report from `nyc` in the console is rather limited. To get a more detailed coverage report you can run `npm run coverage-html-report`. This will produce a html report from the `nyc` data and display it in a browser on your local machine.
+
+To run the integration tests you need to set the `DCC_NEW_TMP_EMAIL` environment variables. E.g.:
+
+```
+$ export DCC_NEW_TMP_EMAIL=https://testrun.org/new_email?t=[token]
+$ npm run test
+```
+
+### Scripts
+
+We have the following scripts for building, testing and coverage:
+
+- `npm run coverage` Creates a coverage report and passes it to `coveralls`. Only done by `Travis`.
+- `npm run coverage-html-report` Generates a html report from the coverage data and opens it in a browser on the local machine.
+- `npm run generate-constants` Generates `constants.js` and `events.js` based on the `deltachat-core-rust/deltachat-ffi/deltachat.h` header file.
+- `npm install` After dependencies are installed, runs `node-gyp-build` to see if the native code needs to be rebuilt.
+- `npm run build` Rebuilds all code.
+- `npm run build:core` Rebuilds code in `deltachat-core-rust`.
+- `npm run build:bindings` Rebuilds the bindings and links with `deltachat-core-rust`.
+- `ǹpm run clean` Removes all built code
+- `npm run prebuildify` Builds prebuilt binary to `prebuilds/$PLATFORM-$ARCH`. Copies `deltachat.dll` from `deltachat-core-rust` for windows.
+- `npm run download-prebuilds` Downloads all prebuilt binaries from github before `npm publish`.
+- `npm test` Runs `standard` and then the tests in `test/index.js`.
+- `npm run test-integration` Runs the integration tests.
+- `npm run hallmark` Runs `hallmark` on all markdown files.
+
+### Releases
+
+The following steps are needed to make a release:
+
+1. Wait until `pack-module` github action is completed
+2. Run `npm publish https://download.delta.chat/node/deltachat-node-v1.x.x.tar.gz` to publish it to npm. You probably need write rights to npm.

+## install node
+
+Download and install `v16` from <https://nodejs.org/en/>
+
+## install rust
+
+Download and run `rust-init.exe` from <https://www.rust-lang.org/tools/install>

+
+`windows-build-tools` will install `Visual Studio 2017` by default and should not mess with existing installations of `Visual Studio C++`.
+
+## get the code

+```
+$ mkdir -p src/deltachat
