Favicon

To replace the default favicon, goto Real Favicon Generator and create yours. Then unzip and copy everything from that file to your website/public/ folder. That should completely replace the default favicon set.

If you just want to replace the favicon.ico and not be bothered with the rest, you will need to remove these files
