You can create new pages e.g. by directly entering the URL like:
part is the page name.
Or you could use the search box - if there isn't a page with the name you entered it will show you:
Create the page "MyUberUnit" on this wiki!
Once you have the edit page open, paste the template stuff in, fill it out, press "preview" to see the results. Once you're happy with it press "save".
Worst case scenario: If you are not getting it to work yourself, send me the template data and text and i'll put it in.
