BetterBook

BetterBook lets modpack creators, server owners, and mod developers write and publish guidebooks without leaving Minecraft. Its visual editor uses the same paper styling as the reader, so you can see how a page will look while you build it. Players read the finished book in a vanilla-inspired, double-page interface with page navigation, a table of contents, and links between pages.
Pages can include formatted text, callouts, steps, code blocks, images, formulas, and diagrams. You can also display Minecraft items, entity models, structures, and custom recipe layouts. Books support clickable navigation and multiple languages.
Publish a .book file to the server, then let players open it with a command, carry a bound copy, or read it from a lectern. Each player can browse a lectern book independently. Bound copies load the current server file when opened, making published guides easy to update.
