Issues adding Nav Bar? Options

Hey all,

starting a new blog using the Attitude Theme,

And across the strip under the header (nav bar?) I wan’t to add the standard “home”, “About” “resources” type pages,

But on my dashboard I am unsure which to use, I have tried the Menu option but this theme only hosts 1 menu I believe?

Then I tried pages, but I’m unsure of how to make a link within this bar.

If anyone could please assist me with a how-to link or quickly typed guide that would be so great,

Thanks for your help in advance!
