+# Hitbox Guard
+
+Hitbox Guard creates a hitbox for your models.
+
+It adds a hidden `hitbox` folder with a hidden `hitbox` cube sized `14 x 32 x 14`, so entity models can keep a consistent hitbox marker without rebuilding it by hand.
+
+## What It Does
+
+- Creates or reuses a `hitbox` folder
+- Creates a `hitbox` cube
+- Uses a `14 x 32 x 14` size
+- Keeps the folder and cube hidden
+- Leaves the cube unlocked
+- Replaces the previous `hitbox` cube when running the action again
+
+## Usage
+
+Open your model, then run:
+
+`Filter > Create Hitbox`
+
