Have you ever wanted to contribute to open source? Or get a project from github and try it out? This talk will give a from-the-ground-up guide covering how to interact with projects on github, to fork and modify them, and (if you wish) how to push your changes back to the original projects. This talk includes practical examples of working with git repositories, branches and pull requests, all delivered by an open source lead who loves helping people through this process. The examples here are from CakePHP - pop in to this session to learn about git and github, and how to contribute to your favourite PHP framework, all in 30 minutes!
