 We use a standard GitHub PR workflow. We run CI on every PR and require all PRs to build without warnings (including clippy and Rustfmt warnings), pass tests, have a DCO sign-off (use `-s` when you commit, the DCO bot will guide you through completing the DCO agreement for your first PR), and have at least one review. If any of this is difficult for you, don't worry about it and ask on the PR.
 
-To run CI-like tests locally, we recommend you run `cargo clippy`, `cargo test`, and `cargo fmt` before submitting your PR. See above for running integration tests, but you probably won't need to worry about this for your first few PRs.
