+## How to write commit messages
+
+We use [Conventional Commit messages](https://www.conventionalcommits.org/) to automate version management.
+
+Most common commit message prefixes are:
+
+* `fix:` which represents bug fixes, and generate a patch release.
+* `feat:` which represents a new feature, and generate a minor release.
+* `feat!:`, `fix!:` or `refactor!:` and generate a major release.
+
+## Releasing
+
+1. Merge the release PR
+2. Run `npm publish`
