-## Usage
+## How to integrate ibc-rs changes into basecoin
+Since basecoin serves as a suite of integration tests against ibc-rs's functionality, each ibc-rs
+PR also requires an accompanying basecoin PR. The steps to do this are:
+1. In a new branch in basecoin, update ibc [revisions][revs] with the latest commit of the ibc-rs PR.
+2. Implement the necessary changes in basecoin in order to get it working with the latest commit revision of ibc-rs.
+3. Run `cargo clippy --all-features` and `cargo clippy --no-default-features` and fix any issues that clippy raises.
+4. Open a PR in the basecoin-rs repository, making sure to the link to the associated ibc-rs PR.
+5. Check to see if the [integration tests][integration-tests] pass.
