+## Development Scripts
+
+#### `yarn release`
+
+> Bump the version
+
+> Push a release to GitHub and npm
+
+> Push a changelog to GitHub
+
+_Notes:_
+
+- Requires authentication with [`npm adduser`](https://docs.npmjs.com/cli/adduser.html)
+- [`auto`](https://github.com/intuit/auto) is used to generate a changelog and push it to GitHub. In order for this to work correctly, **an environment variable called `GH_TOKEN` is needed** that references a [GitHub personal access token](https://help.github.com/en/articles/creating-a-personal-access-token-for-the-command-line) with the appropriate permissions to update the repo.
