First of all I want to think the community for this great project.
Second, I found this H5p client enabling installation of the app in a Node environment (instead of PHP). https://github.com/h5p/h5p-cli/
As I'm a bit noob and not really a developer, I didn't know how to use it. My specific question is regarding the h5p-content/blanks folder. I want to know what goes there exactly to be able to run the app server?
