I'm setting up my server on Ubuntu 18.04 and Apache 2. I'm at the point where I'm setting up PHPMyadmin and the DO guide suggests setting up Let's Encrypt before setting PHPMyAdmin. I'm going to add my domains to my server after setting up PHPmyAdmin. Do I setup Let's Encrypt before setting up PHPMyadmin or set up Let's Encrypt after all my sites have been added to my server?

Thanks
