+### Cutting a new release
+
+Once all changes are merged into `main`, use `cargo release` to cut a new release. This will automatically update the version in `Cargo.toml`, create a new git tag, and push the tag to GitHub.
+
+Given the next release version will be `0.9.0`
+
+```bash
+# dry run to make sure everything looks normal
+cargo release 0.9.0
+
+# execute the release
+cargo release 0.9.0 --execute
