+
+## Build Requirements
+
+- Linux or Mac, scrips make use of features like `>` pipes and `&&` (maybe the newer versions of powershell support them, but I didn't try that.)
+- rust (installed via rustup)
+
+## Start the webserver
+
+The webserver is an example usage. Goal of it is to be usable both as example and as base for deltachat-kaiOS.
+
+```sh
+RUST_LOG=info cargo run --features webserver
+```
+
+## Generate Typescript Bindings
+
+```sh
+cd typescript
+npm i
+npm run build
+```
+
+## Run the development example
+
+Mac
+
+```sh
+alias firefox=/Applications/Firefox.app/Contents/MacOS/firefox
+npm run example:build && firefox --devtools $(pwd)/example/browser-example.html
+```
+
+Linux:
+
+```sh
+npm run example:run
+```
+
+## Compiling server for kaiOS or android:
+
+```sh
+cross build --features=webserver --target armv7-linux-androideabi --release
+```
+
+## Run the tests
+
+### Rust tests
+
+```
+cargo test --features=webserver
+```
+
+### Typescript
+
+```
+cd typescript
+npm run test
+```
+
+For the online tests to run you need a test account token for a mailadm instance,
+you can use docker to spin up a local instance: https://github.com/deltachat/docker-mailadm
+
+> set the env var `DCC_NEW_TMP_EMAIL` to your mailadm token: example:
+> `DCC_NEW_TMP_EMAIL=https://testrun.org/new_email?t=1h_195dksa6544`
+
+If your test fail with server shutdown at the start, then you might have a process from a last run still running probably and you need to kill that process manually to continue.
+
+#### Test Coverage
+
+You can test coverage with `npm run coverage`, but you need to have `DCC_NEW_TMP_EMAIL` set, otherwise the result will be useless because some functions can only be tested with the online tests.
+
+> If you are offline and want to see the coverage results anyway (even though they are NOT correct), you can bypass the error with `COVERAGE_OFFLINE=1 npm run coverage`
+
+Open `coverage/index.html` for a detailed report.
+`bindings.ts` is probably the most interesting file for coverage, because it describes the api functions.

+## Core system
+
+- [X] Base structure of JSON API code 
+- [X] Implement the first methods for testing + the code that should later be generated by the proc macro
+- [X] Create the proc macro
+  - [X] json api
+  - [X] ts types
+    - [X] arguments (no args, one argument, multiple args)
+    - [X] return type
+    - [X] custom types as type aliases that ts file looks prettier
+
+
+## Pre - MVP
+
+- [X] Web socket server
+- [WIP] Web socket client (ts)
+  - [X] backend connection state changed events
+  - [X] Reconnect on connection loss / connection state
+  - [ ] find a way to type the event emitter callback functions
+- [X] Events
+
+## MVP
+
+- [X] mocha integration test for ts api
+ - [X] basic tests
+ - [X] advanced / "online tests" (mailadm for burner accounts)
+- [ ] coverage for a majority of the API
+- [ ] Blobs served
+- [ ] Blob upload (for attachments, setting profile-picture, importing backup and so on)
+- [ ] Web push API? At least some kind of notification hook closure this lib can accept.
+
+## Other Ideas
+
+- [ ] make sure there can only be one connection at a time to the ws 
+  - why? , it could give problems if its commanded from multiple connections
+- [ ] encrypted connection?
+- [ ] authenticated connection?
+- [ ] Look into unit-testing for the proc macros?
+- [ ] proc macro taking over doc comments to generated typescript file
+- [X] GH action for tests (rust and typescript)
+  - [X] rust test
+  - [X] rust fmt
+  - [X] rust clippy
+  - [X] tsc check
+  - [X] prettier
+  - [X] mocha
+- [X] scripts to check&fix prettier formatting

+- When receiving a message: If the key exists, but belongs to another address (we may want to benchmark this)
   AND there is a `Chat-Version` header\
-  AND the message is signed correctly
-  AND the From address is (also) in the encrypted (and therefore signed) headers <sup>[[1]](#myfootnote1)</sup>\
   AND the message timestamp is newer than the contact's `lastseen` (to prevent changing the address back when messages arrive out of order) (this condition is not that important since we will have eventual consistency even without it):
 
   Replace the contact in _all_ groups, possibly deduplicate the members list, and add a system message to all of these chats.
   
   - Note that we can't simply compare the keys byte-by-byte, since the UID may have changed, or the sender may have rotated the key and signed the new key with the old one.
 
-<a name="myfootnote1">[1]</a>: Without this check, an attacker could replay a message from Alice to Bob. Then Bob's device would do an AEAP transition from Alice's to the attacker's address, allowing for easier phishing.
-
-<details>
-<summary>More details about this</summary>
-Suppose Alice sends a message to Evil (or to a group with both Evil and Bob). Evil then forwards the message to Bob, changing the From and To headers (and if necessary Message-Id) and replacing `addr=alice@example.org;` in the autocrypt header with `addr=evil@example.org;`.
-
-Then Bob's device sees that there is a message which is signed by Alice's key and comes from Evil's address and would do the AEAP transition, i.e. replace Alice with Evil in all groups and show a message "Alice changed their address from alice@example.org to evil@example.org". Disadvantages for Evil are that Bob's message will be shown on Alice's device, possibly creating confusion/suspicion, and that the usual "Setup changed for..." message will be shown the next time Evil sends a message (because Evil doesn't know Alice's private key).
-
-Possible mitigations:
-- if we make the AEAP device message sth. like "Automatically removed alice@example.org and added evil@example.org", then this will create more suspicion, making the phishing harder (we didn't talk about what what the wording should be at all yet).
-- Add something similar to replay protection to our Autocrypt implementation. This could be done e.g. by adding a second `From` header to the protected headers. If it's present, the receiver then requires it to be the same as the outer `From`, and if it's not present, we don't do AEAP --> **That's what we implemented**
-
-Note that usually a mail is signed by a key that has a UID matching the from address.
-
-  That's not mandatory for Autocrypt (and in fact, we just keep the old UID when changing the self address, so with AEAP the UID will actually be different than the from address sometimes)

+Otherwise you need to `compile the Delta Chat bindings yourself <#sourceinstall>`_.
 
 We recommend to first `install virtualenv <https://virtualenv.pypa.io/en/stable/installation.html>`_,

-        virtualenv env  # or: python -m venv

 Running tests

-   source env/bin/activate

 You should now be able to build the python bindings using the supplied script::

 The core compilation and bindings building might take a while,
 depending on the speed of 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

 Building manylinux based wheels
-===============================
+====================================
 
 Building portable manylinux wheels which come with libdeltachat.so
-can be done with Docker_ or Podman_.
+can be done with docker-tooling.
 
-.. _Docker: https://www.docker.com/
-.. _Podman: https://podman.io/
+using docker pull / premade images
+------------------------------------
 
-If you want to build your own wheels, build container image first::
+We publish a build environment under the ``deltachat/coredeps`` tag so
+that you can pull it from the ``hub.docker.com`` site's "deltachat"
+organization::
 
-   $ cd deltachat-core-rust # cd to deltachat-core-rust working tree
-   $ docker build -t deltachat/coredeps scripts/coredeps
-
-This will use the ``scripts/coredeps/Dockerfile`` to build
-container image called ``deltachat/coredeps``.  You can afterwards
-find it with::
-
-   $ docker images
+    $ docker pull deltachat/coredeps
 
 This docker image can be used to run tests and build Python wheels for all interpreters::
 
     $ docker run -e DCC_NEW_TMP_EMAIL \
-       --rm -it -v $(pwd):/mnt -w /mnt \
+       --rm -it -v \$(pwd):/mnt -w /mnt \
        deltachat/coredeps scripts/run_all.sh
+
+
+Optionally build your own docker image
+--------------------------------------
+
+If you want to build your own custom docker image you can do this::
+
+   $ cd deltachat-core # cd to deltachat-core checkout directory
+   $ docker build -t deltachat/coredeps scripts/docker_coredeps
+
+This will use the ``scripts/docker_coredeps/Dockerfile`` to build
+up docker image called ``deltachat/coredeps``.  You can afterwards
+find it with::
+
+   $ docker images
+
+
+Troubleshooting
+---------------
+
+On more recent systems running the docker image may crash.  You can
+fix this by adding ``vsyscall=emulate`` to the Linux kernel boot
+arguments commandline.  E.g. on Debian you'd add this to
+``GRUB_CMDLINE_LINUX_DEFAULT`` in ``/etc/default/grub``.
