I am fairly new. So I have already cloned a repo from git hub! Copying this file and pasting it in a different folder and making changes there. Will it affect my original repo?
you first need to clone your project in a directory.
git clone <url>
then do your changes.
and finally do these steps to push your changes.
git add *
git commit -m "some comments about changes"
git push origin master
during the process git might ask for some credential
