Two problems trying to get github project uploaded

program lets me choose a repo then asks for a username and password and I have no idea whoose username and password it wants.
I also choose a folder and it does nothing … It might be flashing something on the screen really fast but in the end the result is nothing. Do you have a suggestion. I really want to get my github project uploaded and work on it.

Hi @abigdreamer,
did you take a look at my github pages video?

Let me know if you still got problems after it.
