Implementing Enplated Email is easy and takes only a few seconds.
You can find it here.
You can also download the full release from GitHub.
<?php
require_once 'EnplatedEmail.php';
$EM = new EM;
...
?>
If the EnplatedEmail.php file is in another folder, you need to specify its path.
You can rename the $EM variable. The documentation uses the name $EM.
You can then start generating your email. More information can be found in the documentation.
