+# HUD bar for `3d_armor` [`hbarmor`]
+
+* Version: 0.2.0
+
+## Description
+This mod adds a simple HUD bar which displays the current damage
+of the player's armor (from the 3D Armor [`3d_armor`] mod) as a percentage (rounded).
+
+100% armor means the armor is in perfect shape. 0% means the armor is almost destroyed
+or non-existant. Note that to reach 100%, the player must wear at least 4 different
+pieces of armor in perfect shape.
+
+The armor bar also does not tell anything about the armor's strength,
+only how worn out it already is.
+
+By default, the armor bar is hidden if the player wears no armor.
+
+## Dependencies
+* HUD bars [`hudbars`], major version 1
+* 3D Armor [`3d_armor`] (tested with Minetest 0.4.14)
+
+## Licensing
+This mod is entirly free softare.
