 ## Usage
 
 Please note that for using this crate's [register definitions](src/registers) (as provided by
-`aarch64_cpu::registers::*`), you need to also include
-[`tock-registers`](https://crates.io/crates/tock-registers) in your project. This is because the
-`interface` traits provided by `tock-registers` are implemented by this crate. You should include
-the same version of `tock-registers` as is being used by this crate to ensure sane
-interoperatbility.

-For example, in the following snippet, `X.Y.Z` should be the same version of `tock-registers` that
-is mentioned in `aarch64-cpu`'s [`Cargo.toml`](Cargo.toml#L23).
