ICON GENERATION INSTRUCTIONS
============================

To generate the extension icons:

METHOD 1 - Using the HTML Generator (Recommended):
1. Open "generate-icons.html" in your web browser
2. Click "Download All Icons" button
3. Save the three files as:
   - icon16.png
   - icon48.png  
   - icon128.png
4. Place them in this folder

METHOD 2 - Create Your Own:
1. Create three PNG images with sizes: 16x16, 48x48, 128x128 pixels
2. Use a green message bubble icon design
3. Name them: icon16.png, icon48.png, icon128.png
4. Place them in this folder

METHOD 3 - Use Online Icon Generator:
1. Go to any online icon generator (e.g., favicon.io)
2. Create icons with green background and message symbol
3. Export in sizes: 16x16, 48x48, 128x128
4. Name and save them here

TEMPORARY SOLUTION:
If you want to test the extension immediately without icons,
you can use any placeholder PNG images with the correct names and sizes.
The extension will still work, just with generic icons.

ICON DESIGN GUIDELINES:
- Background: Green gradient (#22c55e to #16a34a)
- Symbol: White message bubble/chat icon
- Style: Modern, rounded corners
- Format: PNG with transparency (optional)
