The installation of the Social Deals Engine plugin is just like any other plugin installation from WordPress.org. Login to your WordPress site and go to Plugins > Add New.
At the Install Plugins Page enter "Social Deals Engine" into the search box and click on "Search Plugins" or hit Enter.
Select the Social Deals Engine Plugin, click either on "Details" or "Install Now".
Wait until WordPress installed the plugin. After it's done, click on "Activate Plugin".
Now you should see a message “Plugin activated” at the top of the window.
After you successfully installed the plugin you will see a new Admin Menu on the left hand side. It's called "Deals".
Click on the Settings submenu to get to the Plugin's settings page to start setting up the plugin for use.
