This is a Sublime Text package which includes a bunch of handy snippets for doing Codeigniter framework development.
If you have the Package Control package installed, you can install Codeigniter framework Snippets from inside Sublime Text itself. Open the Command Palette and select "Package Control: Install Package", then search for Codeigniter framework Snippets.
If you haven't got Package Control installed you will need to make a clone of this repository into your packages folder, like so:
git clone https://github.com/mpmont/ci-snippets.git ci-snippets
If you find error or wathever just fork it and send me a pull request.
