+## CI
+
+The CI runs a couple of workflows:
+
+### Code
+
+- **[ci]**: A catch-all for small jobs. Currently only runs lints (rustfmt, clippy etc.)
+- **[unit]**: Runs unit tests (tests in `src/`) and doc tests
+- **[integration]**: Runs integration tests (tests in `tests/` and sync tests)
+- **[fuzz]**: Runs fuzz tests
+- **[bench]**: Runs benchmarks
+
+### Docs
+
+- **[book]**: Builds, tests, and deploys the book.
+
+### Meta
+
+- **[deny]**: Runs `cargo deny` to check for license conflicts and security advisories in our dependencies
+- **[sanity]**: Runs a couple of sanity checks on the code every night, such as checking for unused dependencies
+- **[project]**: [GitHub Projects][gh-projects] automation.
