If you’ve been wondering how to get involved in the community’s accelerated development of CodeIgniter, this is the best place to start. It covers everything from how to set up your GitHub account, to Git-Flow, coding and documentation requirements, and the mechanics of making a pull request to the CodeIgniter repository.
