Drawing Chair Structures - Organic Chemistry?

I don't know how to draw the chair conformation of cyclohexane.I know how to draw a chair, but not how to figure out where the substituents go...like where to put them after a ring flip and all that fun stuff..detailed explanations or a website that shows it step by step. PLEASE

In the above link when you see chair conformation of cyclohexane you will find that every carbon of the cyclohexane ring has two hydrogens (or substituents), one of which is in axial conformation (shown in red colour) and other is in equitorial conformation (shown in blue colour). When you flip a chair conformation to other chair conformation the axial substitutent becomes equitorial and equitorial becomes axial, this is also clear in the above link.
