Ocotopress with github repo branch

Ocotopress with github repo branch

I'm new to both Github and Ocotopress. I've made a blog, and i have been
following a tutorial from:
http://schuyler.info/blog/how-to-setup-a-new-octopress-blog-on-github-pages.html
I've used rake generate and then rake deploy - which works a treat. I can
see in my repo the files from _deploy. However, it says this is the master
branch. And i am under the impression it shouldn't be? As the rest of the
folders i added to my source folder don't show up in this site.
I can visit the website via gitpages fine. I can see my two test posts.
But i updated the navigation file within the source folder and tried to
push this but it doesn't seem to appear.
In the tutorial there is a bit:
$ git add .
$ git commit -m "I made a post." -a
$ git push
This doesn't do anything for me. It says:
Everything up-to-date
Even when i am sure it's not.. Can anyone save a damsel in distress?
Note - I don't see any of the commit comments on my repo, so i am figuring
something has gone wrong and my master is not correct.
