Upload local changes on online repository

When working within a project one needs to update files with changes on a specified repository.

As first thing one has to update its local repository with the last changes made to the remote one following these steps

Then, you are ready to upload you changes to the online repository:

git add <file(s)>
git commit -m "<commit_message>"
git push <remote> <branch>

Before pushing your changes, one can add/commit multiple times obtaining different uploads with different commits

Then git credentials will be requested in order to finalize the upload.
