### Git Workflow

Answering the following questions helps you choose a branch workflow:

* Where do important phases of development occur?
* How can you identify (and backport) groups of related change?
* Do you have work which often needs to be updated in multiple distinct long-lived branches?
* What happens when emergency patches are required?
* What should a branch for a particular purpose (including user-tactical) be named?
* What is the lifecycle of a branch?
