Separate page in the "academic" theme?

Firstly, thanks for such an easy-to-go framework as well as the great themes.

I am using the academic theme for my website and while I am able to modify/add contents/sections on my main page, I am not sure how to add a separate page on my website. Basically what I desire is a button in the main.menu navigation (which I can create in the config file) to link to that page. I have tried to search a solution for this but I am not reaching any end. Would anyone using the “academic” theme be kind enough to help me out on this i.e. can I create a separate static page on my website and if so, how?
