Materials and You by Skyla, is a book that you automatically receive after loading a world for the first time since installing the mod. It is used as a method of displaying the tools, materials, forge and how to get started in Tinkers' Construct. Since the release of Tinkers Construct to 1.10.2 the book is no longer split into several Volumes and is therefore much shorter but better organized. It also updates if the original copy is altered [due to an update or other reason (including, but not limited to adding extensions, such as Mechworks)].
The book doesn't give you a detailed introduction on how to begin the mod and states: “Sadly it looks like some pages were lost” in the first pages of the book.
Tools and Materials
This covers the Modifiers that you can add to tools and what they do.
This section goes over what you need to build a working Smeltery.
This section goes over what you need to build a working Seared Furnace.
This section goes over what you need to build a working Tinker Tank.
As stated above the book is automatically received after loading a world for the first time since installing the mod, but if you lose your copy you can always craft a new one.
