Incorporating w/ CodeIgniter

We are wanting to include PatternLab in our CodeIgniter projects.  However, we are unclear on where/how to install in such a way that it all works seamlessly.  Twig isn't finding the templates when we  use them in our CodeIgniter project under the application/views folder.

We really think PatternLab can help us, but we can't get past square one in terms of getting it set up.
