The project is set up to use Grunt the JavaScript Task Runner to make a release.
The generated project includes a package.json that lists the dependencies, but you'll need to run npm install to download them.
The repository expects to be in a mod folder named bAnchorbuttons_dev. The default grunt task builds to bAnchorbuttons_test. The 'production' build is through:
grunt release --target=bAnchorButtons
