How to genuflect.

Is there a correct way to genuflect? I am wondering if it makes a difference what knee hits the floor. Are there any books available with detailed training for Altar Servers?
Thank you so very much.

The proper way to genuflect is to bend your right knee to touch the floor.

A good guide for altar servers:
