how to update github page in multi pos

Requirement

I want to write blog with github page and octopress in the office
and in the home.

Steps

The github page has work well done with pc in the home.
Now setup the environment in office to write github page.
The github page repo:
https://github.com/martinbj2008/martinbj2008.github.io

the octopress is pushed to git repo as branch “source”

How to write blog and sync them to github while avoid conflict with home?

1. clone the ‘source’ branch of github page repo.

The branch includes markdown files and config files.

clone the github page repo and checkout branch `master`
