Thanks! Glad you liked it. This checklist is what I've been going through for the past many months with my startup. Creating the list was a cathartic process and my original audience was meant to be friends who are building their own businesses. Glad to see it's getting more attention now.
I'd be fine with it getting added elsewhere as a more usable checklist as long as there's a link back to the github repo. I plan to update the checklist as I learn about new requirements and/or get pull requests.
