---------------------
   Discord Tickets
---------------------

  A bot created by Eartharoid for the Discord (TM) platform. [GNU-GPLv3.0]

  > The bot manages user-created support tickets to allow your support team to provide quicker
    and better assistance to your community members.

---------------------
     Quick Start
---------------------

  > For detailed instructions, visit the github repository and read the documentation.

  > Assuming you have created discord application, edit 'config.json' to allow the bot to
    function correctly.

  > You will need your bot token (keep it a secret) and channel & role IDs from your server

  > It is recommended that you do not change much / anything in any of the .js files unless
    you know what you are doing, to prevent critical errors from occuring.
