First time making a schematic , and I'm a terrible builder.
the button packages what is inside the barrel and sends it off onto the chain. edit the sign so it goes to the right place. If you have multiple frogs, the checklist will help you list them all. Step on the pressure plate to open the trapdoor and rename the frog and check internals. It can be powered by connecting the chain conveyor to another that has rotation. Be sure to check if the belts are working right
