+
+## Steps
+
+1. Prepare your mod icon. If you don’t already have one, you’ll need to create it.
+2. Resize your mod icon to 256x256 and save the new PNG file as `icon-256.png`.
+3. Move the `icon-256.png` file to your mod's resources folder.
+
+<Files>
+    <Folder name="resources" defaultOpen>
+        <File name="icon-256.png" />
+    </Folder>
+</Files>
+
+| File | Location | File Resolution |
+| -------- | ------- | ----------- |
+| icon-256.png | resources/ | 256x256 |
