Cool - might be worth noting for documentation purposes either here or on #140 or somewhere else that another way to do this is with an empty first commit with just the message? At least that's what I usually do, if I'm understanding #140 correctly. I'm sure some people would prefer either way through so no objection to having both methods

[jerry-skydio]

yeah i prefer that too but there's benefits to the github ui if you do a lot of formatting or attachments
