How do I add more pages to my site?

[Maxs]

Hey there! I'm just a newbie to making websites and sorry if this just sounds so basic to the point to where you won't even reply. But uh basically I wanna make more pages like uh a page to showcase achievments I might add to my site and all that. I might also make a page that displays all the current staff on my site as well as maybe a page that tells you how to apply for staff or mod. Yk?
