I think the repository you asked for is the .zip file posted by @Freagarach in the following thread: Just extract the container and you see the modded files on your drive. By changing those, zipping and uploading you're 'pushing'.

Actually a slavery system could make more expensive units useful again in a non-violence !   I’m specifically interested in the nonviolence mod !

I just saw your similar post... ... and got reminded on this topic: My problem with your proposal is that it shouts 'I minimize micro-management!' but in my game style it would lead to more micro-management bc units would not more be where I garrisoned them and sometimes I need all those 5 units at one place and then I have a problem.

Some modders use their GitHub repositories (e.g. 0ADMODS), some have their mod only on a local drive or their preferred cloud storage and yet other have a Gitea repo (f.e. Empires Besieged). It's impossible to give a general answer.

So to be clear opengl stopped working ?
