HELP PLEASE!

Hi everybody, and in advance I’m sorry for asking such dumb questions, it’s just that I don’t understand how the plugin works.

1 – Do I have to add the hooks to my WordPress code?
2 – If doing so, do those lines of code would create like a simple registering form or that would gather the info from any form I create (e.g. Contact form 7)?
3 – When the affiliate fill the form, the plugin creates the link to be copied?

Honestly, I don’t understand how it works.

Thank you very much!
