+
+## Skins
+
+Your skin is the custom appearance of your player character. Since you don't need to own the game to play here, skins don't load automatically. Use **SkinRestorer** to set your skin in-game:
+
+- `/skin set <username>` — copy the skin of any Minecraft player (e.g. `/skin set Notch`)
+- `/skin set url <url>` — set your skin from a direct image URL
+- `/skin clear` — remove your custom skin
