1996 Nissan Maxima toe out

Suspension problem
1996 Nissan Maxima 6 cyl Front Wheel Drive Automatic 110K miles

Hi thanks and well my issue is im broke and want to fix the toe out of my car. The tires are being worn only on the inside on both sides of the vehicle. You can even see the wheels toe'ing out a bit. How can I do this at home. Or where can I find a book that shows me. Because the one I have sucks and says to take it to mechanic. Even though I know I seen a mechanic adjust something with just a wrench and was telling me that he was just adjusting so the wheel is straight.
