 For example, if you wanted to create the configuration option example below in
 the file `/etc/pure-ftpd/pure-ftpd.conf`:
 
+```puppet
     ChrootEveryone yes
+```
 
 You would declare it like this to the `pureftpd` module:
 
+```puppet
     class { 'pureftpd':
       config => {
         chrooteveryone => 'yes',
       }
     }
+```
 
 The notable exception to that rule is for these `pure-ftpd.conf` options, which
 should not need to be manually declared.  Passing a hash of configuration
 options to the appropriate class parameter automatically defines these options
 for you.
