+1.  Fork the Dot repository
+2.  Create a new branch for each feature or improvement
+3.  Send a pull request from each feature branch to the 3.x branch
 
 It is very important to separate new features or improvements into separate feature branches, and to send a pull request for each branch. This allows me to review and pull in new features or improvements individually.
