+# Release process
+
+1. Create a release branch “release-vX.Y.Z” and submit as a PR.
+  1. Update version in Cargo.toml and Cargo.lock.
+  2. Replace "## main branch" with "## Release {{version}} ({{date}})" in
+     CHANGELOG.md.
+  3. Commit with message: "Release {{version}}."
+2. Create release tag “vX.Y.Z”.
+  1. Get the release notes from CHANGELOG.md, set as the tag body.
+  2. Push tag to origin. The release.yaml workflow will run on GitHub, publish
+     the package to crates.io, and build and publish binaries.
+3. Post-release commit:
+  1. Insert "## main branch" above first "## Release" in CHANGELOG.md.
+  2. Commit with message: "Prepping CHANGELOG.md for development."
+  3. Push to origin.
