Just saw the /zh spawn command and looked on the command reference and in game and it's not clear enough how to spawn a horse. My attempt to spawn a regular horse gave me a mule one time and a llama another time. Every other time was errors due to not being the right string of arguments.

I suggest giving some examples on the commands page on how to use this command and maybe link to a page with more information if such a page exists.

Good idea ! Links to the Tips & tricks page have been added for each complicated command.
