Open a terminal and run the following git command:
git clone "url you just copied"
Now create a branch using the git checkout command:
git checkout -b your-new-branch-name
For example:
git checkout -b hoanganh
Add those changes to the branch you just created using the git add command:
git add name-file-change
Now commit those changes using the git commit command:
git commit -m "Add <your-name> to Contributors list"
replacing <your-name> with your name.
Push your changes using the command git push:
git push origin <add-your-branch-name>
replacing <add-your-branch-name> with the name of the branch you created earlier.
