Well, GitHub is good, gives you collaboration, version tracking, source control. So people don't end up with five different versions of Popup.py where two only fires when robot is entering smartzone, or like, OmniV2, OmniV3, OmniReallyGood, OmniSuperGood.
You can also fork the repo and do your own AIs, fix existing AIs and request them be added into main repo through pull requests.
Way better than trying to reinvent the wheel again on GTM.
