I've struggled with this forever, so here's the full process I've pieced together from many posts:

1. Make an access token for your GitHub account. Click on your profile, go to dev settings, and create a classic token.

2. Check off the following and then click "generate token"

   ✅repo

   ✅workflow

   ✅user

   ✅write:discussion

   ✅admin:enterprise

   ✅admin:gpg_key

3. Double-check that you have added, committed, and merged all changes.

4. In the command line interface, type these commands. Replace <space holders> with your personal information.

   a) git config --global user.email <yourEmail>

   b) git config --global user.name “<yourUrerName”

   c) git remote set-url origin <urlForYourRepo>

   (if no repo currently exists, use this command instead) git remote add origin <urlForYourRepo>

   d) git branch -M main

   e) git push -u origin main

5. Now it should ask for your GitHub username and password. In place of your password, use the access token you made earlier.
