Hi @caxtonacollins, you haven't removed the .git directory in your initialised project root, so I can't see it from here, I'm seeing it as a submodule, use rm -rf .git in your implementation root to remove the directory and push.

I could remember doing this before I pushed.... Because I couldn't push due to the submodule issue. But I will check it out again
