-The core library for Delta Chat, written in Rust
-</p>
+The chatmail core library implements low-level network and encryption protocols, 
+integrated by many chat bots and higher level applications, 
+allowing to securely participate in the globally scaled e-mail server network. 
+We provide reproducibly-built `deltachat-rpc-server` static binaries
+that offer a stdio-based high-level JSON-RPC API for instant messaging purposes. 
+
+The following protocols are handled without requiring API users to know much about them: 
+
+- secure TLS setup with DNS caching and shadowsocks/proxy support 
+
+- robust [SMTP](https://github.com/chatmail/async-imap) 
+  and [IMAP](https://github.com/chatmail/async-smtp) handling
+
+- safe and interoperable [MIME parsing](https://github.com/staktrace/mailparse) 
+  and [MIME building](https://github.com/stalwartlabs/mail-builder). 
+
+- security-audited end-to-end encryption with [rPGP](https://github.com/rpgp/rpgp)
+  and [Autocrypt and SecureJoin protocols](https://securejoin.rtfd.io)
+
+- ephemeral [Peer-to-Peer networking using Iroh](https://iroh.computer) for multi-device setup and
+  [webxdc realtime data](https://delta.chat/en/2024-11-20-webxdc-realtime). 
+
+- a simulation- and real-world tested [P2P group membership
+  protocol without requiring server state](https://github.com/chatmail/models/tree/main/group-membership).

 The JSON-RPC API is exposed in two fashions:

-* A executable that exposes the JSON-RPC API through a [WebSocket](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) server running on localhost.
-* The JSON-RPC API can also be called through the [C FFI](../deltachat-ffi). The C FFI needs to be built with the `jsonrpc` feature. It will then expose the functions `dc_jsonrpc_init`, `dc_jsonrpc_request`, `dc_jsonrpc_next_response` and `dc_jsonrpc_unref`. See the docs in the [header file](../deltachat-ffi/deltachat.h) for details.

 ## Usage

-#### Running the WebSocket server
-
-From within this folder, you can start the WebSocket server with the following command:
-
-```sh
-cargo run --features webserver
-```
-
-If you want to use the server in a production setup, first build it in release mode:
-
-```sh
-cargo build --features webserver --release
-```
-You will then find the `deltachat-jsonrpc-server` executable in your `target/release` folder.
-
-The executable currently does not support any command-line arguments. By default, once started it will accept WebSocket connections on `ws://localhost:20808/ws`. It will store the persistent configuration and databases in a `./accounts` folder relative to the directory from where it is started.
-
-The server can be configured with environment variables:
-
-|variable|default|description|
-|-|-|-|
-|`DC_PORT`|`20808`|port to listen on|
-|`DC_ACCOUNTS_PATH`|`./accounts`|path to storage directory|
-
-If you are targeting other architectures (like KaiOS or Android), the webserver binary can be cross-compiled easily with [rust-cross](https://github.com/cross-rs/cross):
-
-```sh
-cross build --features=webserver --target armv7-linux-androideabi --release
-```
-

-The package includes a JavaScript/TypeScript client which is partially auto-generated through the JSON-RPC library used by this crate ([yerpc](https://github.com/Frando/yerpc/)). Find the source in the [`typescript`](typescript) folder.

After running `npm run build` as documented above, there will be a file `dist/deltachat.bundle.js`. This is an ESM module containing all dependencies. Copy this file to your project and import the DeltaChat class.

 #### Running the example app

-cd typescript
-npm run build
-npm run example:build
-npm run example:start

-
- [ ] different test type to simulate two devices: to test autocrypt_initiate_key_transfer & autocrypt_continue_key_transfer
-
-## MVP - Websocket server&client
-
-For kaiOS and other experiments, like a deltachat "web" over network from an android phone.
-
- [ ] coverage for a majority of the API
- [ ] Blobs served
- [ ] Blob upload (for attachments, setting profile-picture, importing backup and so on)
- [ ] other way blobs can be addressed when using websocket vs. jsonrpc over dc-node
- [ ] Web push API? At least some kind of notification hook closure this lib can accept.
-
-### Other Ideas for the Websocket server
-
- [ ] 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
-
-## Desktop Apis
-
-Incomplete todo for desktop api porting, just some remainders for points that might need more work:
-
- [ ] manual start/stop io functions in the api for context and accounts, so "not syncing all accounts" can still be done in desktop -> webserver should then not do start io on all accounts by default
