Document how we use git and GitHub (and maybe broader engineering guidelines) #22
Description
Is your feature request related to a problem? Please describe.
We're now using a range of GitHub templates, automations, bots, actions etc., which are well understood to those of use who've been around to see them implemented and get involved in the conversations about them. But all this stuff is likely to be confusing to new joiners.
Describe the solution you'd like
Add some READMEs (to a section of this repo or in a new repo) explaining how we use git and GitHub.
Describe alternatives you've considered
We could also broaden this out to cover other aspects of what we expect from engineers to make our engineering culture more explicit.
