Getting started

1. Craft the Structure Encyclopedia: Book + Compass + Amethyst Shard (or take it from the creative tab).
2. Open it with the item or the keybind (default K, configurable).
3. Explore — when you enter a catalogued structure, an action-bar message confirms the unlock.
4. Return to the book to read the page.

Pages start locked as ???. The index is a paged grid of structure icons. Open a page for lore, mobs, and notable loot (icons with hover names). Vanilla coverage ships in the jar.
