-*   `npm install`
-*   Make necessary changes
-*   Update `README.md` and `test.js` if necessary
-*   Run `npm run release`. This command  parses `angular` style commits using `conventional-changelog` to determine the next version for the packages
-*   Alternatively, run `npm run release ${VERSION}` and the release script will use `${VERSION}` as the version number in `package.json`
