This flow chart was not originally my idea. The original idea came from from Nijin, and you can see his own flow chart in the link below:

Reading the flow chart is easy, and the words "true" and "false" - while seemingly trivial - were added when I continued to have difficulty following the lines of Nijin's chart and thought "there must be a faster way to the draw the eye towards the right direction".

A more detailed explanation on reading the flow chart can be found at Nijin's complicated wires walkthrough (link above).
