PathFinder Help

I understand the concept behind the purpose of Pathfinder I’ve just had difficultly fully implementing it. I’ve used wpilib screensteps and Jaci’s Pathfinder Github guide. First is one superior over the other? and within the wpilib screen steps is a method FollowPath. Do I use it outside the code? or is there something I’m just missing?

Both are pretty similar, but screensteps has a few more details (the pathfinder wiki just call this code in your control loop, screensteps puts that code in FollowPath method and shows you how to set up a notifier to run at the required rate instead of leaving that as an exercise to the reader).
