dev/New-Books.md

+If you want to make your own Side Quests, adventures, or whatever, it's pretty simple.
+Make a new git repo for your work, then:
+
+> git submodule add https://gitlab.com/bindrpg/config config
+
+> git submodule update --init
+
+> cp config/main.tex .
+
+Once you have that `main.tex` file, you can start adjusting it and adding whatever you want.
+
+## Referencing External Books
+
+If you want to reference an external book, such as the core book, add this command:
+
+> \externalRefrent{core}
+
+The name of the project should be the default git name, so the core book is 'core', and 'Adventures in Fenestra' is 'aif'.
+Both repositories should be in the same repo, so if you make `myRPG`, then the directory contents should include `core` and `myRPG` for cross-referencing to work properly.
+
+After this, you can write:
+
+> See the core book, \pageref{fate_points} for Fate Points.
+
+...and that reference to the core book will be made automatically.
+
+### Automatic Descriptions
+
+The external reference can also automatically pull in spell descriptions with the `\nameref{}` command.
+Spells all have an alternative header, which is equal to the spell's description.
+
+For example:
+
+> Spell header: Fireball
+
+> Spell description: Fireball Deal 1D6 + Lv + Int Damage.
+
+This means that if you do `\nameref{fireball}`, you get a description of how fireball works.
+This is useful for footnotes, so you can summarize an item quickly, without making the reader stand up and get a rulebook just to follow the passage.
