The Better With Mods Manual is an in-game manual added by Better With Mods. Right-clicking it will open it.
Once opened, the manual will display a starting page of text in which it tells the player basic info about the mod. The manual then lists the two main sections of the mod, the Core mod and the Modules sytem. These sections are further broken down into other features. The Core mod section links to all the Blocks and Items added by the mod, as well as a crash course which talks about mechanics such as Mechanical Power, Stoking a Fire, and more. The Modules section links to all the configurable Hardcore Features, Mod Compatibility features and Tweaks.
