How do I "merge" all my local repo and overwrite what's shown on github?

https://github.com/enjoysmath/BananaCats

Is the repo.  That is waaaayyy old code.  I need to merge in my current code from my local repo, using TortoiseGit.  I’ve tried “merge”.  I am pushing to master just fine.

Any ideas on this?

Solved this, by cloning what’s on github.com, deleting everything locally, copy/pasting in from my local folder all the new stuff, comming and pushing.  Now the changes are there.

Might have been that I was pushing to bitbucket, or something…

I have created a pull request successfully, but couldnt ‘merge request’ and confirm… Need help on this ASAP… its urgent
