Plugin authors sometimes add comments between the <head> tags highlighting the output from their plugin.
If you don't like these comments, for whatever reason, then this plugin will remove them for you.
Specifically comments are removed from the output of the wp_head function so comments in theme templates will not be affected.
The automatic plugin installer should work for most people.
To manually install the plugin:
- Upload the plugin folder to the '/wp-content/plugins/' directory
- Activate the plugin through the 'Plugins' menu in WordPress
