 This crate defines several kinds of weak hash maps and sets. See 
 the [full API documentation](http://docs.rs/weak-table/) for details.
 
-This crate supports Rust version 1.32 and later.
+### Rust version support
+
+This crate supports Rust version 1.46 and later.
+
+### Crate features
+
+`weak-table` is built with the `std` feature, which enables
+functionality dependent on the `std` library, enabled by default.
+Optionally, the following dependency may be enabled:
+
+  - `ahash`: use `ahash`’s hasher rather than the `std` hasher
+
+If the `std` feature is disabled (for no_std) then the `ahash` dependency **must** be enabled.
