I like and use BEM for CSS, it clearly says all about the code and saves time for developers. And I badly wanted something for git as well. I don’t generally delete all the merged branches, I keep some branches which have huge or major code changes/enhancements. So when I look back at them after some time I want to understand what I did in that branch long ago. I am lazy to go through the code or commit message and want my branch name do the story telling about the work I did in that branch.
So, I did a small research and able to construct a beginner naming convention for git branches. You can find it here
