added 'origin' to creating a repo and 'add -A'

Hey Drew:

I added the word 'origin' to the second step of creating a new repo. I also added -A to the third step, but I'm not 100% sure that part is necessary - it's just what I do to make sure all the files in the folder are part of the initial commit.

I think this site is awesome and will come in so handy for so many people! Thanks for making it.
:)
