Trying to make a simple mod to moschops, how to save the mod

I decided to change something about the moschops I Wasn’t happy about but I can’t seem to be able to save the files to a mod, so I can upload it to steam. The moschops will attack on the test map so its nothing to do with the settings, just changed a fw things on ai_moschops and the character one. When I click to upload the feature for uploading mod seems greyed out, would this be very hard to learn to fix, I watched some videos but don’t see to say about configuring existing dinos.

Thanks
