The primary goal of this repository and the code therein is to enable Mozillians to move faster and to be more productive, all while maximizing the quality of work being performed.

We help achieve that goal by providing robust tools that allow developers to spend more time using their brains instead of wrangling with tools, particulary in the area of version control and code management.

This repository aims to provide high-quality software that has a low barrier to change. We achieve this by having comprehensive, easy-to-write and run tests. Robust testing gives us the confidence that we can move fast without breaking things. Doing so allows us to serve the needs of Mozilla better and faster.
