+# `wasm32-wasi-preview2`
+
+**Tier: 3**
+
+The `wasm32-wasi-preview2` target is a new and still (as of January 2024) an
+experimental target. This target is an extension to `wasm32-wasi-preview1` target,
+originally known as `wasm32-wasi`. It is the next evolution in the development of
+wasi (the [WebAssembly System Interface](https://wasi.dev)) that uses the WebAssembly
+[component model] to allow for a standardized set of syscalls that are intended to empower
+WebAssembly binaries with native host capabilities.
+
+[component model]: https://github.com/WebAssembly/component-model

+
+## Requirements
+
+This target is cross-compiled. The target supports `std` fully.
+
+## Platform requirements
+
+The WebAssembly runtime should support the wasi preview 2 API set.
+
+This target is not a stable target. This means that there are only a few engines
+which implement wasi preview 2, for example:
+
+* Wasmtime - `-W component-model`
