GIT How to create a branch and apply changes to server? (for beginners / noobs)

How to create a branch and apply changes to master:

1. On "master" branch, do "git checkout -b new-branch"
2. Do some code changes on that branch, then "git add name-of-file-extension" "git commit -m "your message here"" "git push"
3. I then move back to "master" or main/initial branch, "git checkout master"
4. merge my new branch, "git merge new-branch"
5. Then push/upload changes made in the branch, "git push"
