Initially, the tree pattern deals with the actual assigning a number of a verse into one of the circles of the tree. This process begins at the beginning of the Book of Mormon and continues to the last verse. What we have then is a series of trees. We call this series a system.
This system of trees gives us the ability to read the Book of Mormon in a new light. In the future, I hope to share my thoughts on this. Meanwhile, the complex arrangement of tree patterns creates an incredible number of systems that make it mathematically impossible for Joseph Smith to accomplish this in his short lifetime. This website focuses on the mechanics of this coding, a coding that comes from God and not man.
