git workflow
@atmb4u
1. You MODIFYfiles in your working directory.
2. You STAGEthe files, adding snapshots of them to
your staging area.
3. You do a COMMIT, which takes the files as they
are in the staging area and stores that snapshot
permanently to your git directory.

git config --global user.name "UserName"
●
git config --global user.email “email@example.com”

●
git commit -m “commit message”
git commit

●
Add a remote server location for the repo
●
git remote add origin <remote url>
●
git remote rm origin
git remote

●
git push origin master
remote branch
git push
