Many people seem to be confused how to use Workbench. It requires energy supply but I don't have any ways to produce energy, depending on generators from other mods.

It may help to change config option NoEnergy but no one want to see config, so I think Workbench itself produce very small amount of energy. Then the progress bar doesn't change so it'll be nice if number shows the progress.

Don't forget to tell you can boost the speed if you send FE to the machine. The machine may produce only 10 FE/t.
