-Changes to the UIs
-------------------
-
-- The secondary self addresses (see below) are shown in the UI, but not editable.
-
-- When the user changed the email address in the configure screen, show a dialog to the user, either directly explaining things or with a link to the FAQ (see "Other" below)
-
-Changes in the core
--------------------
-
-- We have one primary self address and any number of secondary self addresses. `is_self_addr()` checks all of them.
-
-- If the user does a reconfigure and changes the email address, the previous address is added as a secondary self address.
-
-  - don't forget to deduplicate secondary self addresses in case the user switches back and forth between addresses).
-
-  - The key stays the same.
-
-- No changes for 1:1 chats, there simply is a new one
-
-- When we send a message to a group, and the primary address is not a member of a group, but a secondary address is:
-  
-  Add Chat-Group-Member-Removed=<old address> and Chat-Group-Member-Added=<new address> headers to this message
-
-  - On the receiving side, make sure that we accept this (even in verified groups) if the message is signed and the key stayed the same
-
-Other
------
-
-- The user is responsible that messages to the old address arrive at the new address, for example by configuring the old provider to forward all emails to the new one.

-Problem: missing eventual group consistency
---------------------------------------------
-
-If group members are concurrently adding new members,
-the new members will miss each other's additions, example:
-
-1. Alice and Bob are in a two-member group
-
-2. Then Alice adds Carol, while concurrently Bob adds Doris
-
-Right now, the group has inconsistent memberships:
-
-- Alice and Carol see a (Alice, Carol, Bob) group
-
-- Bob and Doris see a (Bob, Doris, Alice)
-
-This then leads to "sender is unknown" messages in the chat,
-for example when Alice receives a message from Doris,
-or when Bob receives a message from Carol.
-
-There are also other sources for group membership inconsistency:
-
-- leaving/deleting/adding in larger groups, while being offline,
-  increases chances for inconsistent group membership
-
-- dropped group-membership messages
-
-- group-membership messages landing in "Spam"
-
-
-Note that all these problems (can) also happen with verified groups,
-then raising "false alarms" which could lure people to ignore such issues.
-
-IOW, it's clear we need to do something about it to improve overall
-reliability in group-settings.
-
-
-
-Solution: replay group modification messages on inconsistencies
-------------------------------------------------------------------
-
-For brevity let's abbreviate "group membership modification" as **GMM**.
-
-Delta chat has explicit GMM messages, typically encrypted to the group members
-as seen by the device that sends the GMM. The `Spec <https://github.com/deltachat/deltachat-core-rust/blob/master/spec.md#add-and-remove-members>`_ details the Mime headers and format.
-
-If we detect membership inconsistencies we can resend relevant GMM messages
-to the respective chat.  The receiving devices can process those GMM messages
-as if it would be an incoming message. If for example they have already seen
-the Message-ID of the GMM message, they will ignore the message. It's
-probably useful to record GMM message in their original MIME-format and
-not invent a new recording format. Few notes on three aspects:
-
-- **group-membership-tracking**: All valid GMM messages are persisted in
-  their full raw (signed/encrypted?) MIME-format in the DB. Note that GMM messages
-  already are in the msgs table, and there is a mime_header column which we could
-  extend to contain the raw Mime GMM message.
-
-- **consistency_checking**: If an incoming GMM has a member list which is
-  not consistent with our own view, broadcast a "Group-Member-Correction"
-  message to all members containing a multipart list of GMMs.
-
-- **correcting_memberships**: Upon receiving a Group-Member-Correction
-  message we pass the contained GMMs to the "incoming mail pipeline"
-  (without **consistency_checking** them, to avoid recursion issues)
-
-
-Alice/Carol and Bob/Doris getting on the same page
-++++++++++++++++++++++++++++++++++++++++++++++++++
-
-Recall that Alice/Carol and Bob/Doris had a differening view of
-group membership. With the proposed solution, when Bob receives
-Alice's "Carol added" message, he will notice that Alice (and thus
-also carol) did not know about Doris.  Bob's device sends a
-"Chat-Group-Member-Correction" message containing his own GMM
-when adding Doris. Therefore, the group's membership is healed
-for everyone in a single broadcast message.
-
-Alice might also send a Group-member-Correction message,
-so there is a second chance that the group gets to know all GMMs.
-
-Note, for example, that if for some reason Bobs and Carols provider
-drop GMM messages between them (spam) that Alice and Doris can heal
-it by resending GMM messages whenever they detect them to be out of sync.
-
-
-Discussions of variants
-++++++++++++++++++++++++
-
-- instead of acting on GMM messages we could send corrections
-  for any received message that addresses inconsistent group members but
-  a) this could delay group-membership healing
-  b) could lead to a lot of members sending corrections
-  c) means we might rely on "To-Addresses" which we also like to strike
-     at least for protected chats.
-
-- instead of broadcasting correction messages we could only send it to
-  the sender of the inconsistent member-added/removed message.
-  A receiver of such a correction message would then need to forward
-  the message to the members it thinks also have an inconsistent view.
-  This sounds complicated and error-prone.  Concretely, if Alice
-  receives Bob's "Member-added: Doris" message, then Alice
-  broadcasting the correction message with "Member-added: Carol"
-  would reach all four members, healing group consistency in one step.
-  If Bob meanwhile receives Alice's "Member-Added: Carol" message,
-  Bob would broadcast a correction message to all four members as well.
-  (Imagine a situation where Alice/Bob added Carol/Doris
-  while both being in an offline or bad-connection situation).

-simplify/streamline mark-seen/delete/move/send-mdn job handling
----------------------------------------------------------------
-
-Idea: Introduce a new "msgwork" sql table that looks very
-much like the jobs table but has a primary key "msgid"
-and no job id and no foreign-id anymore. This opens up
-bulk-processing by looking at the whole table and combining
-flag-setting to reduce imap-roundtrips and select-folder calls.
-
-Concretely, these IMAP jobs:
-
-    DeleteMsgOnImap
-    MarkseenMsgOnImap
-    MoveMsg
-
-Would be replaced by a few per-message columns in the new msgwork table:
-
-- needs_mark_seen: (bool) message shall be marked as seen on imap
-- needs_to_move: (bool) message should be moved to mvbox_folder
-- deletion_time: (target_time or 0) message shall be deleted at specified time
-- needs_send_mdn: (bool) MDN shall be sent
-
-The various places that currently add the (replaced) jobs
-would now add/modify the respective message record in the message-work table.
-
-Looking at a single message-work entry conceptually looks like this::
-
-    if msg.server_uid==0:
-        return RetryLater  # nothing can be done without server_uid
-
-    if msg.deletion_time > current_time:
-        imap.mark_delete(msg)  # might trigger early exit with a RetryLater/Failed
-        clear(needs_deletion)
-        clear(mark_seen)
-
-    if needs_mark_seen:
-        imap.mark_seen(msg)    # might trigger early exit with a RetryLater/Failed
-        clear(needs_mark_seen)
-
-    if needs_send_mdn:
-        schedule_smtp_send_mdn(msg)
-        clear(needs_send_mdn)
-
-    if any_flag_set():
-        retrylater
-    # remove msgwork entry from table
-
-
-Notes/Questions:
-
-- it's unclear how much we need per-message retry-time tracking/backoff
-
-- drafting bulk processing algo is useful before
-  going for the implementation, i.e. including select_folder calls etc.
-
-- maybe it's better to not have bools for the flags but
-
-  0 (no change)
-  1 (set the imap flag)
-  2 (clear the imap flag)
-
-  and design such that we can cover all imap flags.
-
-- It might not be neccessary to keep needs_send_mdn state in this table
-  if this can be decided rather when we succeed with mark_seen/mark_delete.

-# Webxdc Developer Reference
-
-## Webxdc File Format
-
-- a **Webxdc app** 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 app 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);
-```
-
-Webxdc apps are 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.summary`: optional, short text, shown beside app 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 `send_update`) 
-
-- `update.summary`: optional, short text, shown beside app icon (see `send_update`)
-
-
-### 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 App Name"
-```
-
-- **name** - The name of the app.
-  If no name is set or if there is no manifest, the filename is used as the app name.
-
-
-## App Icon
-
-If the ZIP-root contains an `icon.png` or `icon.jpg`,
-these files are used as the icon for the app.
-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 app -
-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)
-
-
-## 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
-- 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.

+Installing bindings from source (Updated: 20-Jan-2020)
+=========================================================
+
+Install Rust and Cargo first.  Deltachat needs a specific nightly
+version, the easiest is probably to first install Rust stable from
+rustup and then use this to install the correct nightly version.
+
+Bootstrap Rust and Cargo by using rustup::
+
+   curl https://sh.rustup.rs -sSf | sh
+
+Then GIT clone the deltachat-core-rust repo and get the actual
+rust- and cargo-toolchain needed by deltachat::
+
+   git clone https://github.com/deltachat/deltachat-core-rust
+   cd deltachat-core-rust
+   rustup show
+
+To install the Delta Chat Python bindings make sure you have Python3 installed.
+E.g. on Debian-based systems `apt install python3 python3-pip
+python3-venv` should give you a usable python installation.
+
+Ensure you are in the deltachat-core-rust/python directory, create the
+virtual environment and activate it in your shell::
+
+   cd python
+   python3 -m venv venv  # or: virtualenv venv
+   source venv/bin/activate
+
+You should now be able to build the python bindings using the supplied script::
+
+   ./install_python_bindings.py
+
+The installation might take a while, depending on your machine.
+The bindings will be installed in release mode but with debug symbols.
+The release mode is currently necessary because some tests generate RSA keys
+which is prohibitively slow in non-release mode.
+
+After successful binding installation you can install a few more
+Python packages before running the tests::
+
+    python -m pip install pytest pytest-timeout pytest-rerunfailures requests
+    pytest -v tests
+
+
+running "live" tests with temporary accounts
+---------------------------------------------
+
+If you want to run "liveconfig" functional tests you can set
+``DCC_NEW_TMP_EMAIL`` to:
+
+- a particular https-url that you can ask for from the delta
+  chat devs. This is implemented on the server side via
+  the [mailadm](https://github.com/deltachat/mailadm) command line tool.
+
+- or the path of a file that contains two lines, each describing
+  via "addr=... mail_pw=..." a test account login that will
+  be used for the live tests.
+
+With ``DCC_NEW_TMP_EMAIL`` set pytest invocations will use real
+e-mail accounts and run through all functional "liveconfig" tests.
+
+
 Installing pre-built packages (Linux-only)
