Create a branch: git checkout -b <branch name>.
Push it upstream to remote: git push -u origin <branch name>.
If you’re working on multiple branche, keep them up to date with the main branch.
First make sure local is up to date with remote with git update.
Then on the feature branch, do git merge main.
When you’re ready to merge the feature into main, first catch it up to main as in the previous paragraph.
Then git checkout main, and git merge <feature branch>.
Finally, to detele the feature branch if you are done with it, do git branch -d <feature branch>
and git push origin --delete <feature branch>.
Last, check the list of branches with git branch -a.
