-                For performance considered:
-                1. This module only check damage_type inside this checklist.
-                2. The permission is checked by cache.
-

-                                
-                For example, 
-                If you want to protect all the players from fall damage, you should do:
-                1. add `minecraft:fall` into the `damage_type_checklist`.
-                2. grant the permission for players: `/lp group default permission set fuji.protect.minecraft:fall`
-                                
-                If you grant permission `/lp group default permission set fuji.protect.*`, then it means cancel
-                all the damage types inside the `damage_type_checklist`.

+

+                - damage

+

+                You can set a meta by: `/lp group default meta set fuji.multiplier.damage.minecraft:zombie 2`
+                
+                - Example 2
+                If you want to cancel fall damage for all players. You can use `damage multiplier`.
