How to remove or overwrite a repository that I created?

[Latitia Graham]

Hello,

I created a DB project repository by cloning files from a network directory. I would like to undo or at least re-do what I did. However, at this point I can't do another clone, it just copies what's already in the repository. Can someone assist me with deleting what I did or with an overwrite?

Also, I do not see a delete or remove option on my project page.

Update: I just attempted git revert 'commit number' in git command. I got  126 files changed, 8500 deletions(-) as the results. However, I still see the all the files in the repo URL. Does git revert take some time to reflect on the website?
