I’m using the plugin on a development or staging site
The license key is only required for live websites, so if you’re using the plugin on a development or staging site, just ignore these instructions for now. You only need to activate your license key on the live website.
Activating the license key on your live site
After installing the paid plugin, go to the Grids > Settings page and fill in your license key at the top. Save the settings to activate.
Activating your license key will make sure you get reminded of automatic updates.
