Once you have installed the plugin, go to Appearance – Widgets and add the CMF Ads widget. You can then choose the options for this widget. You will be asked for the site ID – you can get this by going to the CMF Ads Control Panel and clicking Get Widget next to the site you’re working on.
The plugin is only available to those of you with a self-hosted WordPress blog.
