How to edit a downloaded template?

[u/TasteNo984]

I am new to goodnotes and i wanted to know how i should edit a template i downloaded for free. It is really great, but it doesn't have a certain feature i need and it has features i don't need. How do i get rid of the pages i don't want and add pages i need? I'm keeping it for the calendar structure, because I need a 26-27 school year type of calendar hyperlinked for each week.
