This project contains only the Springboard-specific modules. It is not a ready-to-use Springboard package. We provide packages on this project's releases page.
If you'd like to build Springboard manually, you should checkout the Springboard-Build project, and use drush make to create the package.
You should only need to checkout this repo directly if you want to contribute to the code. If you would like to regularly contribute to Springboard, consider working for us.
