+Icon Placeholder Files
+
+These are simple placeholder SVG icons. Replace them with proper PNG icons:
+
+icon16.png  - 16x16 pixels
+icon32.png  - 32x32 pixels
+icon48.png  - 48x48 pixels
+icon128.png - 128x128 pixels
+
+You can create these icons using:
+1. Online tools like https://www.canva.com or https://www.figma.com
+2. Convert an emoji to PNG at https://emoji.to.png or similar
+3. Use a simple design with a wrench/gear icon
+
+Recommended design:
+- Dark background (#1a1a1a)
+- Green accent color (#4CAF50)
+- Wrench or gear symbol
