I want this plugin in CakePHP but not sure where to start from?

Hey,

I have spent 3 days on this just because there's no documentation and no start point. I want to integrate this as a plugin in my existing CakePHP base LMS. I am experienced in developing WordPress plugins but from your plugin, I am not able to understand which file is the main file from where you are calling and including libraries (content types). I searched through various forum topics on H5P.org but there is no simple and straight rule mentioned anywhere.

Can you please help me in doing this as my project is getting delayed.

One I get this done, I will make sure to write steps and post in this community so that nobody else gets delayed in projects.
