I\'ve been looking at some guides on how to do this but nothing I\'ve tried is working. What I\'ve done so far:
You have origin as a remote created already, just add your stuff to the staging area using git add . then use git commit -m 'your commit message' to commit your changes, then the most important part, PUSH your master branch to your remote using git push origin master.
You should read about the git workflow, here: http://git-scm.com/book/en/Getting-Started-Git-Basics, http://marklodato.github.io/visual-git-guide/index-en.html.
