-
-- introduce per-contact profile images to send out 
-  own profile image heuristically, and fix sending
-  out of profile images in "in-prepare" groups. 
-  this also extends the Chat-spec that is maintained
-  in core to specify Chat-Group-Image and Chat-Group-Avatar
-  headers. thanks @r10s and @hpk42.
-
-- fix merging of protected headers from the encrypted
-  to the unencrypted parts, now not happening recursively
-  anymore.  thanks @hpk and @r10s
-
-- fix/optimize autocrypt gossip headers to only get 
-  sent when there are more than 2 people in a chat. 
-  thanks @link2xt
-
-- fix displayname to use the authenticated name 
-  when available (displayname as coming from contacts 
-  themselves). thanks @simon-laux
-
-- introduce preliminary support for offline autoconfig 
-  for nauta provider. thanks @hpk42 @r10s
-
-## 1.0.0-beta.15
-
-- fix #994 attachment appeared doubled in chats (and where actually

-
-## 1.0.0-beta.14
-
-- fix packaging issue with our rust-email fork, now we are tracking
-  master again there. hpk42
-
-## 1.0.0-beta.13

-- fix #976 -- unicode-issues in display-name of email addresses. @hpk42
-
-- fix #985 group add/remove member bugs resulting in broken groups.  @hpk42
-
-- fix hanging IMAP connections -- we now detect with a 15second timeout
-  if we cannot terminate the IDLE IMAP protocol. @hpk42 @link2xt
-
-- fix incoming multipart/mixed containing html, to show up as
-  attachments again.  Fixes usage for simplebot which sends html
-  files for users to interact with the bot. @adbenitez @hpk42 
-
-- refinements to internal autocrypt-handling code, do not send
-  prefer-encrypt=nopreference as it is the default if no attribute
-  is present.  @linkxt 
-
-- simplify, modularize and rustify several parts 
-  of dc-core (general WIP). @link2xt @flub @hpk42 @r10s
-
-- use async-email/async-smtp to handle SMTP connections, might
-  fix connection/reconnection issues. @link2xt 
-
-- more tests and refinements for dealing with blobstorage @flub @hpk42 
-
-- use a dedicated build-server for CI testing of core PRs
-
-
-## 1.0.0-beta.12
-
-- fix python bindings to use core for copying attachments to blobdir
-  and fix core to actually do it. @hpk42
-
-## 1.0.0-beta.11
-
-- trigger reconnect more often on imap error states.  Should fix an 
-  issue observed when trying to empty a folder.  @hpk42
-
-- un-split qr tests: we fixed qr-securejoin protocol flakyness 
-  last weeks. @hpk42
-
-## 1.0.0-beta.10
-
-- fix grpid-determination from in-reply-to and references headers. @hpk42
-
-- only send Autocrypt-gossip headers on encrypted messages. @dignifiedquire
-
-- fix reply-to-encrypted message to also be encrypted. @hpk42
-
-- remove last unsafe code from dc_receive_imf :) @hpk42
-
-- add experimental new dc_chat_get_info_json FFI/API so that desktop devs
-  can play with using it. @jikstra
-
-- fix encoding of subjects and attachment-filenames @hpk42
-  @dignifiedquire . 
-
-## 1.0.0-beta.9
-
-- historic: we now use the mailparse crate and lettre-email to generate mime
-  messages.  This got rid of mmime completely, the C2rust generated port of the libetpan 
-  mime-parse -- IOW 22KLocs of cumbersome code removed! see 
-  https://github.com/deltachat/deltachat-core-rust/pull/904#issuecomment-561163330
-  many thanks @dignifiedquire for making everybody's life easier 
-  and @jonhoo (from rust-imap fame) for suggesting to use the mailparse crate :) 
-
-- lots of improvements and better error handling in many rust modules 
-  thanks @link2xt @flub @r10s, @hpk42 and @dignifiedquire 
-
-- @r10s introduced a new device chat which has an initial
-  welcome message.  See 
-  https://c.delta.chat/classdc__context__t.html#a1a2aad98bd23c1d21ee42374e241f389
-  for the main new FFI-API.
-
-- fix moving self-sent messages, thanks @r10s, @flub, @hpk42
-
-- fix flakyness/sometimes-failing verified/join-protocols, 
-  thanks @flub, @r10s, @hpk42
-
-- fix reply-to-encrypted message to keep encryption 
-
-- new DC_EVENT_SECUREJOIN_MEMBER_ADDED event 
-
-- many little fixes and rustifications (@link2xt, @flub, @hpk42)
-
-
-## 1.0.0-beta.8
-
-- now uses async-email/async-imap as the new base 
-  which makes imap-idle interruptible and thus fixes
-  several issues around the imap thread being in zombie state . 
-  thanks @dignifiedquire, @hpk42 and @link2xt. 
-
-- fixes imap-protocol parsing bugs that lead to infinitely
-  repeated crashing while trying to receive messages with
-  a subjec that contained non-utf8. thanks @link2xt
-
-- fixed logic to find encryption subkey -- previously 
-  delta chat would use the primary key for encryption
-  (which works with RSA but not ECC). thanks @link2xt
-
-- introduce a new device chat where core and UIs can 
-  add "device" messages.  Android uses it for an initial
-  welcome message. thanks @r10s
-
-- fix time smearing (when two message are virtually send
-  in the same second, there would be misbehaviour because
-  we didn't persist smeared time). thanks @r10s
-
-- fix double-dotted extensions like .html.zip or .tar.gz  
-  to not mangle them when creating blobfiles.  thanks @flub
-
-- fix backup/exports where the wrong sql file would be modified,
-  leading to problems when exporting twice.  thanks @hpk42

-- several rPGP cleanups, security fixes and better multi-platform support 
-
-- reconnect on io errors and broken pipes (imap)
-
-- probe SMTP with real connection not just setup
-
-- various imap/smtp related fixes
-
-- use to_string_lossy in most places instead of relying on valid utf-8
-  encodings
- 
-- rework, rustify and test autoconfig-reading and parsing 
-
-- some rustifications/boolifications of c-ints 
-
-
-## 1.0.0-beta.1 
-
-- first beta of the Delta Chat Rust core library. many fixes of crashes
-  and other issues compared to 1.0.0-alpha.5.
-
-- Most code is now "rustified" and does not do manual memory allocation anymore. 
-
-- The `DC_EVENT_GET_STRING` event is not used anymore, removing the last
-  event where the core requested a return value from the event callback. 
-
-  Please now use `dc_set_stock_translation()` API for core messages
-  to be properly localized. 
-
-- Deltachat FFI docs are automatically generated and available here: 
-  https://c.delta.chat 
-
-- New events ImapMessageMoved and ImapMessageDeleted

 # Continuous Integration Scripts for Delta Chat
 
-Continuous Integration, run through CircleCI and an own build machine.
-
-## Description of scripts 
-
-- `../.circleci/config.yml` describing the build jobs that are run
-  by Circle-CI
-
-- `remote_tests_python.sh` rsyncs to a build machine and runs
-  `run-python-test.sh` remotely on the build machine. 
-
-- `remote_tests_rust.sh` rsyncs to the build machine and runs
-  `run-rust-test.sh` remotely on the build machine. 
-
-- `doxygen/Dockerfile` specifies an image that contains
-  the doxygen tool which is used by `run-doxygen.sh` 
-  to generate C-docs which are then uploaded 
-  via `ci_upload.sh` to `https://c.delta.chat/_unofficial_unreleased_docs/<BRANCH>`
-  (and the master branch is linked to https://c.delta.chat proper). 
+Continuous Integration is run through CircleCI
+but is largely independent of it. 
 
 
-## Triggering runs on the build machine locally (fast!)
+## Generating docker containers for performing build step work 
 
-There is experimental support for triggering a remote Python or Rust test run 
-from your local checkout/branch. You will need to be authorized to login to 
-the build machine (ask your friendly sysadmin on #deltachat freenode) to type::
+All tests, docs and wheel building is run in docker containers:
 
-    ci_scripts/manual_remote_tests.sh rust
-    ci_scripts/manual_remote_tests.sh python
+- **coredeps/Dockerfile** specifies an image that contains all 
+  of Delta Chat's core dependencies as linkable libraries. 
+  It also serves to run python tests and build wheels 
+  (binary packages for Python). 
 
-This will **rsync** your current checkout to the remote build machine 
-(no need to commit before) and then run either rust or python tests. 
+- **doxygen/Dockerfile** specifies an image that contains
+  the doxygen tool which is used to generate C-docs. 
 
-# Outdated files (for later re-use)
+To run tests locally you can pull existing images from "docker.io",
+the hub for sharing Docker images::
 
-`coredeps/Dockerfile` specifies an image that contains all 
-of Delta Chat's core dependencies. It used to run 
-python tests and build wheels (binary packages for Python)
+    docker pull deltachat/coredeps
+    docker pull deltachat/doxygen 
 
-You can build the docker images yourself locally
+or you can build the docker images yourself locally
 to avoid the relatively large download:: 
  
     cd ci_scripts  # where all CI things are 
     docker build -t deltachat/coredeps docker-coredeps
     docker build -t deltachat/doxygen docker-doxygen 
+
+## ci_run.sh (main entrypoint called by circle-ci)
+
+Once you have the docker images available 
+you can run python testing, documentation generation 
+and building binary wheels:: 
+
+    sh DOCS=1 TESTS=1 ci_scripts/ci_run.sh 
+    
+## ci_upload.sh (uploading artifacts on success) 
+
+- python docs to `https://py.delta.chat/_unofficial_unreleased_docs/<BRANCH>`
+
+- doxygen docs to `https://c.delta.chat/_unofficial_unreleased_docs/<BRANCH>`
+
+- python wheels to `https://m.devpi.net/dc/<BRANCH>`
+  so that you install fully self-contained wheels like this:
+  `pip install -U -i https://m.devpi.net/dc/<BRANCH> deltachat`

 =========================
 
 This package provides bindings to the deltachat-core_ Rust -library
-which implements IMAP/SMTP/MIME/PGP e-mail standards and offers
-a low-level Chat/Contact/Message API to user interfaces and bots.
+which provides imap/smtp/crypto handling as well as chat/group/messages
+handling to Android, Desktop and IO user interfaces.
 
+Installing pre-built packages (linux-only)
+==========================================
 
-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 bindings from source
+===============================
+
+If you can't use "binary" method above then you need to compile
+to core deltachat library::
+
+    git clone https://github.com/deltachat/deltachat-core-rust
+    cd deltachat-core-rust
+    cd python
+
+If you don't have one active, create and activate a python "virtualenv":
+
+    python virtualenv venv  # or python -m venv
+    source venv/bin/activate
+
+Afterwards ``which python`` tells you that it comes out of the "venv"
+directory that contains all python install artifacts. Let's first
+install test tools::
+
+    pip install pytest pytest-timeout pytest-rerunfailures requests
+
+then cargo-build and install the deltachat bindings::
+
+    python install_python_bindings.py
+
+The bindings will be installed in release mode but with debug symbols.
+The release mode is necessary because some tests generate RSA keys
+which is prohibitively slow in debug mode.

-Locations can be attachted to messages using
-[standard kml-files](https://www.opengeospatial.org/standards/kml/)
-with well-known names.
-
-
-## User locations
-
-To send the location of the sender,
-the app can attach a file with the name `location.kml`.
-The file can contain one or more locations.
-Apps that support location streaming will typically collect some location events
-and send them together in one file.
-As each location has an independent timestamp,
-the apps can show the location as a track.
-
-Note that the `addr` attribute inside the  `location.kml` file
-MUST match the users email-address.
-Otherwise, the file is discarded silently;
-this is to protect against getting wrong locations,
-eg. forwarded from a normal MUA.
