+# WASI API Bindings for Rust
 
 This package contains experimental [WASI](https://github.com/WebAssembly/WASI)
 API bindings in Rust.
@@ -10,3 +10,15 @@ There are two modules:
 
  - `wasi_unstable`, which provides thin wrappers around the raw functions
    which use idiomatic Rust types rather than raw pointers, and are safe.
+
+This crate is quite low-level and provides conceptually a "system call"
+interface. In most settings, it's better to use the Rust standard library,
+which has WASI support.
+
+To compile Rust projects to wasm using WASI, use the `wasm32-wasi` target,
+like this:
+
+```
+rustup target add wasm32-wasi
+cargo build --target wasm32-wasi
