+description = """
+Rewinds the world and player state to the last checkpoint when the player dies. Blocks, containers, entities, weather, time, dimensions, and inventory are restored to their state at the checkpoint.
+
+### How it works
+- **Return by Death:** On fatal damage, the world rolls back to the last checkpoint instead of showing the death screen.
+- **Checkpoints:** An initial checkpoint is created when entering a world. New checkpoints are saved automatically during safe periods, after combat, and after defeating a boss, or on a fixed timer.
+- **Multiplayer modes:** Supports single key player, multiple key players, all players, or rotating key player, with an optional rollback cooldown.
+- **Manual control:** With cheats enabled, `F6` (`/rzero set`) creates a checkpoint, `F7` (`/rzero load`) rolls back, and `F8` switches the key player mode.
+
+Settings and keybinds are in **Options > Mods**.
