We are a monthly event and we already host our challenges in a git repo even when not using CTFd: https://github.com/montrehack/challenges
It would be nice if ctfcli would have detected that it was already in a git tree and wouldn't do anything about it. For now, I'm going to create a distinct repo for our event but I wanted to let you know of that use case.
This tool is a very nice addition to the CTFd ecosystem by the way! Thanks!
