Castle tutorial

Hi, I have just started Blender so my question will seem stupid, but if you don’t know you have to ask
I am trying to do the Building a Castle tutorial from Blender3d.org, the Tower i can do but the next step has me baffled.
It says leave edit,return to top view, & add a mesh circle with 5 sides. How to I do get the 5 sides on a circle. Any help will be appreciatd. Thanks

just add a circle it will prompt you for a number put there 5 or whatever is needed for the shape you want, i think it is this simple.

Thanks for that, I knew it would be simple but not that simple.
