When I was on CurseForge I saw that there was a wiki with a guide on how to play. I used the guide and then found a problem, it says to build a Heat Generator but when I try to find it, it does not seem to be in the game. I looked at other guides and it seems that they all say to start with the heat generator. Is this a bug on my side, the guide is outdated, or is it a bug in the mod? Not sure what it is but hopefully, someone can help me out because I just want to play the game well.

Version:
Forge 14.23.5.2847
Mekanism V9 I believe
Minecraft 1.12.2

Thank You very much!

Sorry to take up you're time, I found out that you need another mod for the generators. Sorry
