Code comments

To add comments to your Puppet code, use shell-style or hash comments.

Hash comments begin with a hash symbol (#) and continue to the end of a line. You can start comments either at the beginning of a line or partway through a line that began with code. 
# This is a comment
file {'/etc/ntp.conf': # This is another comment
  ensure => file,
  owner  => root,
}
