I uploaded a project written in React to github pages, what should I prescribe to update it? That is, to update the page on this free hosting, how to push a new code. Tried to find the answer, unsuccessfully, I think some of you have come across this know the solution.

git pull
git add .
git commit -m "update"
git push
