Ok well the simple get started quick version. Go to the Auctioneer open up the menu and hit the Arrow in the top left corner of the screen. this will start scanning the auctions Every item every price ect ect. do this 2 - 3 times a day for about a week to get a good baseline value of what items are worth. Then Hit the tab that says BTM scanner or Bottom scanner. Then hit play it will scan the auctions for under priced items then it will pop up with an item and give you informationm about it.
