+=====================================
+
+Depends: default
+
+Recommends: inventory_plus or unified_inventory (use only one)
+
+Adds craftable armor that is visible to other players. Each armor item worn contributes to
+a player's armor group level making them less vulnerable to weapons.
+
+Armor takes damage when a player is hurt but also offers a percentage chance of healing.
+Overall level is boosted by 10% when wearing a full matching set.
+
+Fire protection added by TenPlus1 when using crystal armor if Ethereal mod active, level 1
+protects against torches, level 2 for crystal spike, level 3 for fire, level 5 for lava.
+
+Configuration
+-------------
+
+Armor can be configured by adding a file called armor.conf in 3d_armor mod and/or world directory.
+see armor.conf.example for all available options.
+
+Note: worldpath config settings override any settings made in the mod's directory.
