1. Upload the video-overlayer folder to the /wp-content/plugins/ directory
2. Activate the Video Overlayer Plugin through the 'Plugins' menu in WordPress
3. Configure the plugin by going to the Video Overlayer menu located in the "Settings" section of your WP Dashboard.

Using Video Overlayer

By default the Video Overlay Plugin, when active, will overlay all supported iFrame video embeds with a light-gray video image. In the Video Overlay admin page you can either select an alternate image or select "Custom" and then add a direct link to your custom overlay image.

You can also just set Video Overlay to make your iFrame video embeds fully responsive, leaving off the overlay image. This is ideal for basic Responsive Video Embed functionality.

Removing the Video Overlayer plugin

To remove the Video Overlayer plugin just go to the Plugins page in your dashboard (or the Network Admin dashboard if you're running a multi-blog setup) and click the "Delete" link.
