Questions about setting up and PDF

Hi!

For each new feature on the page (as a link to the next course, etc.) I have to add a new corresponding shortcode?

You can make the pages show PDF page that I have ever done? My course is all in PDF.

How do I display the link “View lessons”?

As the administrator enrolls a student? I do not want the student has to sign up for yourself.

There are some video teaching create the course with the plugin?

Thank you very much.
