+Jarust is just an umbrella crate for `jarust_core`, `jarust_plugins` and `jarust_interface`.

+## Core
+
+The core provides high-level api to connect, create session, attach, detach, ...
+
+It relies on abstractions from the interface crate, meaning we can provide our own implementation of `JanusInterface` and
+pass it to the core, for example, to use the RabbitMQ interface.
+
+## Interface
+
+It contains the core data structures; errors, responses, and messages as well as the transport that communicates with
+the janus server. The transport is abstract, so to create a new transport we can implement the `JanusInterface` trait
+then provide it to the connect functions.
+
+The transaction generation is also abstract with 2 built-in ones, UUID v4 and random string.
+
+## Plugins
+
+Plugins wraps the generic handle from the core crate and adds the plugin specific functionalities and event parsing,
+while also has a handle `Deref` to add unsupported functionalities.
+
+## Runtime
+
+We're trying to be runtime agnostic so we created `jarust_rt` that abstracts the runtime, but currenctly only tokio is supported.
+
+Any task spawing should be from `jarust_rt::spawn` function.

-Internally uses WebSockets to connect to Janus. But you can provide your own transport.
+Jarust is a memory safe and high-performance Rust adapter for [Janus WebRTC server](https://github.com/meetecho/janus-gateway).
+Inspired by [Janode](https://github.com/meetecho/janode), jarust offers similar functionalities but it's designed
+to be customizable, for exmaple, you could use the built-in WebSocket transport or provide your own RabbitMQ transport implementation. For more details about the architecture check [ARCHITECTURE](./ARCHITECTURE.md).
 
 The library wraps the Janus core API and some of the most popular plugins APIs.
 
 The supported Janus plugins currently are:
 
 - EchoTest
 - AudioBridge
-- VideoBridge
 - Streaming
+- VideoRoom
+
+The supported interfaces are:
+
+- WebSocket
+- Restful
