Browse source 
This makes it easier to use the type just by reading the man page and also
treats FreeBSD's MOTD better.

@ -10,6 +10,13 @@ DESCRIPTION
-----------
This cdist type allows you to easily setup /etc/motd.
.. note::
In some OS, motd is a bit special, check `motd(5)`.
Currently Debian, Devuan, Ubuntu and FreeBSD are taken into account.
If your OS of choice does something besides /etc/motd, check the source
and contribute support for it.
Otherwise it will likely just work.
REQUIRED PARAMETERS

If supplied, copy this file from the host running cdist to the target.
If source is '-' (dash), take what was written to stdin as the file content.
If not supplied, a default message will be placed onto the target.

# Supply source file from a different type

Take this kiss upon the brow!
And, in parting from you now,
Thus much let me avow-
You are not wrong, who deem
That my days have been a dream
