+
+The code in this package interacts with the
+<https://github.com/rust-lang/team/> repository.
+
+The `TeamRepo` trait is used to abstract away the HTTP client for testing
+purposes. The `TeamRepoImpl` struct is the actual implementation of
+the trait.
+
+If the `mock` feature is enabled, a `MockTeamRepo` struct is available,
+which can be used for testing purposes. This struct is generated automatically
+by the [`mockall`](https://docs.rs/mockall) crate.
