My new Github page isn't showing up

So I'm following this guide here to create a Github page

I created a repository, cloned it to my project directory and pushed, finally got to this last step:

Fire up a browser and go to http://username.github.io. Give it a couple of minutes for your page to show up—there will be a delay this very first time. In the future, changes will show up pretty much instantly.

My Github repo link is this: https://github.com/leongaban/gabanco

So I assumed my Github page link would be either:
http://leongaban.gabanco.github.io/

or

http://leongaban.github.io/

However neither link is working at the moment :(

Anyone create a Github page before? Eventually I want to try out Jekyll on it.

Rename your repository to <yourusername>.github.io as explained in the documentation.

To publish a user site, you must create a repository owned by your user account that's named <user>.github.io.

Edit: You can only use your own account name for a User or Org Pages repository. A repository like joe/bob.github.io will not build Pages.
