Firstly, download your the plugins files from your CodeCanyon account in the downloads section.
On the backend of your website, go to Plugins > Add new.
Next, click on ‘Upload plugin’ at the top of the page, and then drag and drop your file to the ‘Choose file’ button. Alternatively, you can click ‘Choose file’ and find your file through the file explorer.
Once the plugin has been added, click activate – and you’re good to go!
