I created a repository in the github After that I created a file in a github and cloned it. I pushed it to the main branch. I created another branch and another file "two.txt" by using "git checkout -b new" command. To push the current branch and set the remote as upstream is used "git push --set-upstream origin new" command. Whichhelped me push the new branch and changes into the git. I used rebase command git rebase main new to rebase both branches. And pushed everything again just to be sure. After that I checkd the status using "git status". And everything was uptodate.
