To add your own book gui to the Book Display registry, you first need to add Book Display to your dev enviroment as a dependency.

repositories {
    // ...
    maven {
        name 'Astavie' // You can name it whatever you want
        url 'https://raw.githubusercontent.com/Astavie/Astavie.github.io/mvn-repo/'
    }
}

dependencies {
    // ...
    compile 'astavie:bookdisplay:<version>:deobf'
}

Next, you register your book gui with BookDisplay.register(predicate, factory);

A java 8 predicate, with an ItemStack as its input. This predicate should return true if the ItemStack opens your book gui on a right click.

A java 8 function, with an ItemStack as its input and an IBookWrapper as its output (more on them later). Returns an instance of IBookWrapper using the ItemStack previously checked against.

BookWrapper is a class that transforms a GuiScreen instance into an overlay that can be drawn on the ingame gui. Its constructor has two parameters: gui, a new instance of your book gui, and drawsBackground, a boolean. If your GUI draws a grey background when its opened, you should put true here, so Book Display can remove the background in the overlay.

If you want to add page scrolling, you should override the left() and right() methods. These methods should switch the page, either to the left or right of the current page.

Sometimes, there are buttons in your GUI that you don't want to display on the overlay. In the makeButtonInvisible(button) method, you can choose per button which ones should be made invisible.

IBookWrapper is an interface that contains rendering methods that are invoked when drawing the ingame gui. The class contains 5 extra methods you need to override, apart from left() and right().

This method should draw the gui on the left or right side of the screen as specified by the side parameter. If you want to use rendering methods from the vanilla Gui class, you can simply make your wrapper extend Gui.

Invoked when the window resolution changes.

Invoked when the overlay is opened, before its been rendered.

Invoked every tick while the overlay is opened.

Invoked when the overlay is closed, after its been rendered.
