- Download the .zip package you get after purchasing the plugin;
- From your admin area, navigate to Plugins > Add New;
- Locate the Upload Plugin button at the top-left side of the page and click on it;
- Click on Choose file and locate the .zip package you’ve downloaded, then click on Install Now;
