[The Wowhead Client is a little application we use to keep our database up to date, and to provide you with some nifty extra functionality on the website!]  

[It serves 2 main purposes:]  

1. [It maintains a WoW addon called the Wowhead Looter, which collects data as you play the game!]  
2. [It uploads the collected data to Wowhead in order to keep the database up-to-date!]  

[You can also use it to keep track of your completed quests, recipes, mounts, companion pets, and titles!] 

[So, what are you waiting for? Download the client and get started.]
