 ## Usage
 
-Basic usage involves using a [kube-rs Client] to perform operations on
-[Gateway API resources]. You can either use a basic `Client` to perform
-operations, or you can build a [Controller]. See the `gateway-api/examples/`
-directory for examples.
+This library is intended to be paired with [kube-rs]. Use a [Client] to perform
+operations on [Gateway API resources]. This enables you to build [Controllers],
+so you can create a [Gateway API Implementation] in Rust. See the
+`gateway-api/examples/` directory for example code.
