    Don't mind the messy code. I did try searching on google for a solid amount of time to no avail. I know it's a really simple fix I just don't know the issue. Thanks for reading.

    @johnny_boy Code is not important for this issue.
    Your plugin.yml lacks some formatting,
    Usage needs two more spaces.
