 ## WASI 0.2
 
+### Presentation
+
 WASI 0.2 is the most recent WASI release. APIs designed for WASI 0.2 and the Component Model are defined with the [**WebAssembly Interface Type (WIT)**](https://github.com/WebAssembly/component-model/blob/main/design/mvp/WIT.md) Interface Description Language (IDL). WIT API definitions are made in `.wit` files which are composed into Wasm component binaries. The following interfaces are included in WASI P2:
 
-| API          | Repository                                     | Version |
-| ------------ | ---------------------------------------------- | ------- |
-| I/O          | https://github.com/WebAssembly/wasi-io         | 0.2.0   |
-| Clocks       | https://github.com/WebAssembly/wasi-clocks     | 0.2.0   |
-| Random       | https://github.com/WebAssembly/wasi-random     | 0.2.0   |
-| Filesystem   | https://github.com/WebAssembly/wasi-filesystem | 0.2.0   |
-| Sockets      | https://github.com/WebAssembly/wasi-sockets    | 0.2.0   |
-| CLI          | https://github.com/WebAssembly/wasi-cli        | 0.2.0   |
-| HTTP         | https://github.com/WebAssembly/wasi-http       | 0.2.0   |

-You can explore the types and definitions for a given WASI 0.2 API in its WIT files. When you're ready to start using the API, you will typically generate bindings between the WIT definitions and the language you will be compiling to Wasm. For more information on WIT, see the [WIT section of the Component Model documentation](https://component-model.bytecodealliance.org/design/wit.html).
