+This crate aims to expose a core set of useful randomness primitives. For more niche algorithms, consider using the [`fastrand-contrib`] crate alongside this one.
+
 # Features
 
 - `std` (enabled by default): Enables the `std` library. This is required for the global
   generator and global entropy. Without this feature, [`Rng`] can only be instantiated using
-  the [`with_seed`](Rng::with_seed) method.
+  the [`with_seed`](https://docs.rs/fastrand/latest/fastrand/struct.Rng.html#method.with_seed) method.
+- `js`: Assumes that WebAssembly targets are being run in a JavaScript environment.
