+
+An overlay UI for importing and exporting squad uniforms in Dwarf Fortress.
+
+Overview
+--------
+
+This tool adds an interface overlay to the squad equipment screen, allowing you to easily save and load uniform setups.
+
+Usage
+-----
+
+To use the overlay:
+
+1. Press ``q`` to open the squad sidebar.
+2. Select a squad by checking its checkbox.
+3. Click the ``Equip`` button.
+4. Either:
+   - Click ``Add uniform`` to create a new one, **or**
+   - Click a unit’s ``Details`` button to customize their equipment.
+5. The ``[Import]`` and ``[Export]`` buttons will now appear in the **bottom-right** corner of the screen.
+   - You can also use hotkeys:
+     - ``Ctrl+I`` to import a uniform
+     - ``Ctrl+E`` to export the current uniform
+
+Uniforms are saved to and loaded from the following folder:
+
+``Dwarf Fortress\dfhack-config\squad_uniform``
