To start on a feature or bugfix, head to its issue page (if it's not there, create it and link to any relevant discussions) and assign yourself using the "Assignees" dropdown.
A new branch will automatically be created here, which you can then checkout on your local machine by running git fetch and then git checkout <branch name>.
Branches that have not been worked on for over 4 months will be reassigned to someone else, in order to keep development active.
TBD
(here we can write out where commands are stored, how the database and other infrastructure works, etc)
