You should read the link that followed with HB when you bought it

Here's a link for you, it's how to use HB in general.

And here's a link for all the other guides.
Honorbuddy Guides
And here's a link for the profiles page.
Honorbuddy Profiles
A quick how to lvl:
What lvl is your current chars? (It's lvl XX aka. 80 in this case) so you should go under the 80-85 profiles ..
What is your faction? (It's either horde or alliance, depending on your character's faction.. pick one of them.)
How can i lvl? There are; Questing profiles, Grinding profiles, archaeology, Battlegrounds, etc. etc. etc.
Pick one of the above, (i intentionally didn't tell you which one to go for, because it's in my opinion that people got to learn it themself.. build up your own knowledge of the bot and it's capabilities.. and work from there)
Now! you should have chosen a suitable profile, put it inside your HB folder (i put mine in my default profiles folder).
Load up HB.exe
Look back at the profile page, and see if it's a questing profile or grinding profile (or w/e it is)
pick the appropiate botbase (up in the top right corner.)
aka. I have chosen a grinding profile, so i pick grind bot in the bot bases.
Load profile, (pick the one you've chosen)
fiddle with the settings (those are selfexplanatory)
hit start
Enjoy..
If you're not completely retarded, you should be able to use that as a guide.
