'Invalid plugin.yml'

Hi,
I am very new to the world of plugin development and have been following this tutorial:
I copied the tutorial exactly however, when I launch the server (with the plugin on it) I get this message: "[19:12:17 ERROR]: Could not load 'plugins/Superheat.jar' in folder 'plugins'
org.bukkit.plugin.InvalidDescriptionException: Invalid plugin.yml." The plugin.yml is exactly the same as the one in the tutorial so I don't understand what the problem is.

The download for the plugin: https://www.dropbox.com/s/ci2onlhq7kkxzcm/Superheat.jar

The download for the plugin.yml: https://www.dropbox.com/s/vh05mbj8lfh3jt0/plugin.yml.txt

Thankyou for your time.

 

Post your plugin.yml

 

plugin.yml:

Code:

   
    name: Superheat
    main: me.callumlk00.sh.Superheat
    version: 1.0.0
    description: Superheat turns stone into stone.
    author: callumlk00
    

 

It must be:

Code:

name: Superheat
version: 1.0
author: callumlk00
 
main: //Main path
commands:
  youcommand:
    description: //Your descrption
    usage:

 

The inside of his plugin.yml is right HOWEVER he called it

plugin.yml.txt

instead of

plugin.yml
