To help keep myself honest, I wanted to set up automated test runs on a few personal projects I host on Github. At first I gave Travis a try, since a number of projects I contribute to use it, but it felt a bit clunky. When I found Github had a new CI system in beta, I signed up for the beta and was accepted a few weeks later.

While it is still in development, the configuration language feels lean and powerful. In comparison, Travis's configuration language has obviously evolved over time with some features not interacting properly (e.g. matrix expansion only working on the first job in a workflow using build stages). While I've never felt like I had a complete grasp of the Travis configuration language, the single page description of Actions configuration language feels complete.
