+Create a local copy of the [model-checking fork](https://github.com/model-checking/verify-rust-std) of the Rust Standard Library. The fork comes with Kani configured, so all you'll need to do is to call Kani's building-block APIs (such as
 `assert`, `assume`, `proof` and [function-contracts](https://github.com/model-checking/kani/blob/main/rfc/src/rfcs/0009-function-contracts.md) such as `modifies`, `requires` and `ensures`) directly.
 
 For example, insert this module into an existing file in the core library, like `library/core/src/hint.rs` or `library/core/src/error.rs` in your copy of the library. This is just for the purpose of getting started, so you can insert in any existing file in the core library if you have other preferences.
