I thought I was supposed to use something like Host Gator or something?

This i info shows my computer being the server. Is that correct?

yes the link is for your computer

if you have a host – then what is the exact problem?
if you read the 5 minute instructions you will see what you need to do

also, most hosts – like hostgator have a one click install for wordpress in their control panels

Okay… So I have hostgator.

Where is this one click install for wordpress in their control panel?

HELP!!!

it comes free with your hostgator account. you can even contact them and they will do it immediately for you. WordPress is the simplest software to install on any OS.
