It tries to tell you not to follow the guide because you’ll likely do it wrong and to instead do it the easy way.

And now it says

> **Note:** `./discourse-setup` will enable Let’s Encrypt. And as of March 2017, you can run it again, and press return a few times and enter your email address ; the script will include the required templates and insert your email address as required. Unless you are an expert sysadmin and know a reason not to do that, you should run `discourse-setup` rather than read any further. (If you installed Discourse a _long time ago_ , you might still have to edit `app.yml` by hand.)
