+# Release Process
+
+This documents our release process.
+
+## Update the Code
+
+Checkout `master` and make sure to pull all the latest changes that sould be included in the release.
+
+## Bump the Version
+
+Use [`npm version`](https://docs.npmjs.com/cli/v6/commands/npm-version) to bump the version and update the changelog.
+Most of the time you will want to run:
+
+```
+npm version <patch|minor|major>
+```
+
+For more details and other possible release types see [the npm docs](https://docs.npmjs.com/cli/v6/commands/npm-version).
+
+This will:
+
+1. Create and checkout a branch for the release preparation: `prepare-v<new-version>-<timestamp>`
+1. Bump the version in `package.json` and `package.lock.json`
+1. Update the changelog
+1. Commit the changes and push the branch
+1. If you have the [GitHub CLI](https://cli.github.com/) installed it will automatically open a _draft_ pull request to `master`
+
+## Merge the Release Pull Request
+
+This is a good point to clean up the changelog if needed and get feedback on the release.
+When everyone is happy with the release, merge the pull request to `master`.
+
+## Tag the Release
+
+Back on `master`, tag the release and based on the new tag crate a release on GitHub.
+This is a step we might automate completely via GitHub Actions in the future.
