-**A**ndroid **D**ebug **B**ridge (ADB) client implementation in pure Rust !
+Main features of this library:
 
-Main features :
-
-- Full Rust, no need to use `adb *` shell commands
-- Currently only support server TCP/IP protocol
+- Full Rust, don't use `adb *` shell commands to interact with devices
+- Supports
+  - Using ADB server as a proxy (standard behavior when using `adb` CLI)
+  - Connecting directly to end devices (without using adb-server)
+    - Over **USB**
+    - Over **TCP/IP**
+- Implements hidden `adb` features, like `framebuffer`
 - Highly configurable
+- Provides wrappers to use directly from Python code
 - Easy to use !
 
 ## adb_client
 
-Rust library implementing ADB protocol and providing high-level abstraction over commands.
+Rust library implementing both ADB protocols (server and end-devices) and providing a high-level abstraction over the many supported commands.
 
-Improved documentation [here](./adb_client/README.md).
+Improved documentation available [here](./adb_client/README.md).
 
 ## adb_cli
 
-Rust binary providing an improved version of `adb` CLI, using `adb_client` library. Can be used as an usage example of the library.
+Rust binary providing an improved version of Google's official `adb` CLI, by using `adb_client` library.
+Provides a "real-world" usage example of this library.
 
-Improved documentation [here](./adb_cli/README.md).
+Improved documentation available [here](./adb_cli/README.md).
 
-## Missing features
+## pyadb_client
 
-- USB protocol (Work in progress)
+Python wrapper using `adb_client` library to export classes usable directly from a Python environment.
 
-All pull requests are welcome !
+Improved documentation available [here](./pyadb_client/README.md)
