Learning how to make bots is a huge deal. You can create very specific, and advanced bots that will do better for you, than what you can find anywhere on the forums.
Just try to make a simple bot at first.
Or he could just download a bot for Lebot(*.dmbot) and convert it into a bot for grimoire(*.gbot).
It's pretty straightforward and simple to do. Just click the thing on the right side if Grimoire, click the dmbot you want to convert and viola. Done.
