white balance shots

[XXXmen]

I have an xti camera with the basic portrait lense. I recently took pictures inside a home and most of it came out yellow. I had the WB(white balance)
on AUTO. Can someone explain how to set your own custom white balance
in a step by step process for an xti camera. Thanks.

You might want to read your manual first before asking for step-by-step instructions.
