 There are multiple options to enable SSL:
 
-* using [letsencrypt](https://letsencrypt.org/)
+* using [letsencrypt](https://letsencrypt.org/) (recommended)
 * using self-signed certificates with the provided tool
 
-## let's encrypt
+After installation, you can test your setup with [checktls.com](https://www.checktls.com/TestReceiver).
 
-To enable Let's Encrypt on your mail server, you have to add en environment variable `DMS_SSL` with value `letsencrypt` (see `docker-compose.yml.dist`)
-You also have to mount your `letsencrypt` folder to `/etc/letsencrypt` and it should look like that:

+To enable Let's Encrypt on your mail server, you have to:
 
-You don't have anything else to do.
+* get your certificate using [letsencrypt client](https://github.com/letsencrypt/letsencrypt)
+* add an environment variable `DMS_SSL` with value `letsencrypt` (see `docker-compose.yml.dist`)
+* mount your `letsencrypt` folder to `/etc/letsencrypt`
+
+You don't have anything else to do. Enjoy.
 
 ## self signed certificates
 
 You can easily generate a self-signed SSL certificate by using the following command:
 
-  docker run -ti --rm -v "$(pwd)"/postfix/ssl:/ssl -h mail.my-domain.com -t tvial/docker-mailserver generate-ssl-certificate
+    docker run -ti --rm -v "$(pwd)"/postfix/ssl:/ssl -h mail.my-domain.com -t tvial/docker-mailserver generate-ssl-certificate
 
-  # Press enter
-  # Enter a password when needed
-  # Fill information like Country, Organisation name
-  # Fill "my-domain.com" as FQDN for CA, and "mail.my-domain.com" for the certificate.
-  # They HAVE to be different, otherwise you'll get a `TXT_DB error number 2`
-  # Don't fill extras
-  # Enter same password when needed
-  # Sign the certificate? [y/n]:y
-  # 1 out of 1 certificate requests certified, commit? [y/n]y
+    # Press enter
+    # Enter a password when needed
+    # Fill information like Country, Organisation name
+    # Fill "my-domain.com" as FQDN for CA, and "mail.my-domain.com" for the certificate.
+    # They HAVE to be different, otherwise you'll get a `TXT_DB error number 2`
+    # Don't fill extras
+    # Enter same password when needed
+    # Sign the certificate? [y/n]:y
+    # 1 out of 1 certificate requests certified, commit? [y/n]y
 
-  # will generate:
-  # postfix/ssl/mail.my-domain.com-key.pem (used in postfix)
-  # postfix/ssl/mail.my-domain.com-req.pem (only used to generate other files)
-  # postfix/ssl/mail.my-domain.com-cert.pem (used in postfix)
-  # postfix/ssl/mail.my-domain.com-combined.pem (used in courier)
-  # postfix/ssl/demoCA/cacert.pem (certificate authority)
+    # will generate:
+    # postfix/ssl/mail.my-domain.com-key.pem (used in postfix)
+    # postfix/ssl/mail.my-domain.com-req.pem (only used to generate other files)
+    # postfix/ssl/mail.my-domain.com-cert.pem (used in postfix)
+    # postfix/ssl/mail.my-domain.com-combined.pem (used in courier)
+    # postfix/ssl/demoCA/cacert.pem (certificate authority)
 
 Note that the certificate will be generate for the container `fqdn`, that is passed as `-h` argument.
 Check the following page for more information regarding [postfix and SSL/TLS configuration](http://www.mad-hacking.net/documentation/linux/applications/mail/using-ssl-tls-postfix-courier.xml).
 
-If a matching certificate (files listed above) is found in `postfix/ssl`, it will be automatically setup in postfix and courier-imap-ssl. You just have to place them in `postfix/ssl` folder.
+To use the certificate:
 
+* add an `DMS_SSL=self-signed` to your container environment variables
+* if a matching certificate (files listed above) is found in `postfix/ssl`, it will be automatically setup in postfix and courier-imap-ssl. You just have to place them in `postfix/ssl` folder.
