Sensei certificates comes with a default certificate template which you can use to award learners without having to create one yourself.
To use the default template edit the course you’d like to include a certificate with and choose the Example Template from the drop-down menu in the right side-bar under Certificate Template.
If you change/delete the Example Template, and need to reinstall it, you can simply navigate to Sensei > Data Updates in the WordPress admin panel where you will see a list of updates available for Sensei and for Sensei extensions. Select the Re-run Update button for the Create Master Certificate Template item. This will start the script to recreate the example certificate template. Please note that when you run this function it will reset and assign the example certificate template to ALL courses.
