Well lets assume I have an account on GitHub called MyAccount(placeholder really, but hope it helps a bit), and I have a folder on my own desktop located at C:\Users\Username\Documents\GitHub\MyRepository. After I create this repository in Git GUI, what can I do to actually upload files within the MyRepository folder to GitHub? Is there no way to do this in IDEs like Netbeans? I am a bit lost when it comes down to command prompt though.
