 Here's the most direct way to get your work merged into the project:
 
 * Fork the project.
-* Clone down your fork ( `git clone git://github.com/<username>/jekyll.git` ).
+* Clone down your fork ( `git clone git@github.com:<username>/jekyll.git` ).
 * Create a topic branch to contain your change ( `git checkout -b my_awesome_feature` ).
 * Hack away, add tests. Not necessarily in that order.
 * Make sure everything still passes by running `rake`.
