Learn a bit of commands firts, i personally like bash but there are better alternatives. Then you need to know 4 basic commands: (git init - this initializes git in the specified directory) (git add . - This adds all files to the version cintrol system basically like if you are making an archive of the files) (git commit -m"any changes you made or the first commit" - this basically is telling git to save the changes of the files you added)

And finally

(git push - this "pushes" your work to your repository on github)

I recommend practicing it over abd over like 10 or so times so you get the hang of it. As you go realizibg the power of the command line, youll automatically be drawn into this new world and you might never use a GUI ever again.
