In the WordPress Admin dashboard select Plugins->Add new
You should now see a screen with a list of popular plugins as determined by WordPress.org. At the top left is a button labelled Upload Plugin. Click on it.
You should see a dialog box asking for the plugin file. Navigate to your desktop and choose the file you downloaded in the first step of this procedure then click the Open button at the bottom of the dialog box
You should now be back in the main Add plugin screen with the filename filled out. Just click the Install Now button.
If all goes well you will see a new screen with a link that says Activate Plugin. Click on it. That will complete the plugin installation process.
The plugin is now installed and you should now see an option at the top of the plugin screen to get you started with the configuration wizard.
Completing The Wizard
Once the plugin has been installed and activated, there will be an option at the top of the plugins screen to get you started with a configuration wizard. Click the blue CLICK HERE button to get started.
When you click that button you will be immediately presented with a configuration “wizard” screen. Follow the instructions on the screen to configure your menus, products, departments and more:
Time Saving Tip: Make sure you have at least one menu already configured in your WordPress APPEARANCE->MENUS screen. Otherwise you will have to exit the wizard to create a menu and then start the wizard all over again.
If you get a “directory already exists” error message, you will need to use FTP to upload the updated plugin to the folder that already exists. Check with your hosting provider for instructions on how to use FTP to upload files. Please make sure you “unzip” the plugin files before uploading them via FTP. Alternatively, you can go to the PLUGINS screen and delete the existing plugin before starting the upload process all over again as described above.
Watch the video
The video below will show you some of the installation process. Unfortunately its based on an earlier version of Awesome Support that did not have the initial configuration wizard. However, it does cover some post installation steps that might be useful such as adding an agent.
