+Install [`cargo-bolero`](https://github.com/camshaft/bolero) with
+```sh
+$ cargo install cargo-bolero

+
+Run fuzzing tests with
+```sh

 ## Features
 
 - `vendored`: When using Openssl for TLS, this bundles a vendored version.
 - `nightly`: Enable nightly only performance and security related features.
 
+## Update Provider Data

+To add the updates from the

+# deltachat-jsonrpc
+
+This crate provides a [JSON-RPC 2.0](https://www.jsonrpc.org/specification) interface to DeltaChat.
+
+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.
+
+We also include a JavaScript and TypeScript client for the JSON-RPC API. The source for this is in the [`typescript`](typescript) folder. The client can easily be used with the WebSocket server to build DeltaChat apps for web browsers or Node.js. See the [examples](typescript/example) 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
+```
+
+#### Using the TypeScript/JavaScript client
+
+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. 
+
+To use it locally, first install the dependencies and compile the TypeScript code to JavaScript:
+```sh
+cd typescript
+npm install
+npm run build
+```
+
+The JavaScript client is not yet published on NPM (but will likely be soon). Currently, it is recommended to vendor the bundled build. 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.
+
+
+```typescript
+import { DeltaChat } from './deltachat.bundle.js'
+const dc = new DeltaChat('ws://localhost:20808/ws')
+const accounts = await dc.rpc.getAllAccounts()
+console.log('accounts', accounts)
+```
+
+A script is included to build autogenerated documentation, which includes all RPC methods:
+```sh
+cd typescript
+npm run docs
+```
+Then open the [`typescript/docs`](typescript/docs) folder in a web browser.
+
+## Development
+
+#### Running the example app
+
+We include a small demo web application that talks to the WebSocket server. It can be used for testing. Feel invited to expand this.
+
+```sh
+cd typescript
+npm run build
+npm run example:build
+npm run example:start
+```
+Then, open [`http://localhost:8080/example.html`](http://localhost:8080/example.html) in a web browser.
+
+Run `npm run example:dev` to live-rebuild the example app when files changes.
+
+### Testing
+
+The crate includes both a basic Rust smoke test and more featureful integration tests that use the TypeScript client.
+
+#### Rust tests
+
+To run the Rust test, use this command:
+
+```
+cargo test
+```
+
+#### TypeScript tests
+
+```
+cd typescript
+npm run test
+```
+
+This will build the `deltachat-jsonrpc-server` binary and then run a test suite against the WebSocket server.
+
+The test suite includes some tests that need online connectivity and a way to create test email accounts. To run these tests, talk to DeltaChat developers to get a token for the `testrun.org` service, or use a local instance of [`mailadm`](https://github.com/deltachat/docker-mailadm).
+
+Then, set the `DCC_NEW_TMP_EMAIL` environment variable to your mailadm token before running the tests.
+
+```
+DCC_NEW_TMP_EMAIL=https://testrun.org/new_email?t=yourtoken npm run test
+```
+
+#### Test Coverage
+
+Running `npm run test` will report test coverage. For the coverage to be accurate the online tests need to be run.
+
+> If you are offline and want to see the coverage results anyway (even though they are inaccurate), you can bypass the errors of the online tests by setting the `COVERAGE_OFFLINE=1` environment variable.
+
+A summary of the coverage will be reported in the terminal after the test run. Open `coverage/index.html` in a web browser for a detailed report.

+# TODO
+
+- [ ] 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

+# Delta Chat RPC python client
+
+RPC client connects to standalone Delta Chat RPC server `deltachat-rpc-server`
+and provides asynchronous interface to it.
+
+## Getting started
+
+To use Delta Chat RPC client, first build a `deltachat-rpc-server` with `cargo build -p deltachat-rpc-server`.
+Install it anywhere in your `PATH`.
+
+## Testing
+
+1. Build `deltachat-rpc-server` with `cargo build -p deltachat-rpc-server`.
+2. Run `PATH="../target/debug:$PATH" tox`.
+
+Additional arguments to `tox` are passed to pytest, e.g. `tox -- -s` does not capture test output.
+
+## Using in REPL
+
+Setup a development environment:
+```
+$ tox --devenv env
+$ . env/bin/activate
+```
+
+It is recommended to use IPython, because it supports using `await` directly
+from the REPL.
+
+```
+$ pip install ipython
+$ PATH="../target/debug:$PATH" ipython
+...
+In [1]: from deltachat_rpc_client import *
+In [2]: rpc = Rpc()
+In [3]: await rpc.start()
+In [4]: dc = DeltaChat(rpc)
+In [5]: system_info = await dc.get_system_info()
+In [6]: system_info["level"]
+Out[6]: 'awesome'
+In [7]: await rpc.close()
+```
