Helps with memorising git commands and flags to get you going a bit faster in the terminal. Knowing some of the ins and outs of git is good for getting into a flow state quicker when working (what I mean here is that grepping back through your bash history or googling for that command or flag you need doesn’t interrupt you, you can remain focussed on writing the code). Covers some deeper bits of git as well (i.e. use of bisect). Built from the book Pro Git, shared standards at different places I’ve worked and hints/tricks I’ve picked up from others that I’ve wanted to memorise.
