 ## Usage
 
+### Async
+
+Starting from 0.3, mlua supports async/await for all Lua versions. This feature works using Lua [coroutines](https://www.lua.org/manual/5.3/manual.html#2.6) and require running [Thread](https://docs.rs/mlua/latest/mlua/struct.Thread.html).
+
+**Examples**:
+- [HTTP Client](examples/async_http_client.rs)
+- [TCP Server](examples/async_tcp_server.rs)
+
 ### Choosing Lua version
 
 The following features could be used to choose Lua version: `lua53` (default), `lua52`, `lua51` and `luajit`.
