This is a deliberately brief TL;DR style overview of the steps you might want to take to explore the contents of this repository. It assumes that you're wanting to use the SAP Business Application Studio (App Studio) as your development environment.
We're working through these steps on the Hands-on SAP Dev show, in the series Getting the most out of the SAP TechEd Developer Keynote repository. Check out the 📺 video links against each of the steps to see directly related content from those episodes.
