# To use this, you need Python 3.5+ and pip.
#
#     1. Make a new Discord app with a bot. https://discordapp.com/developers/applications/
#
#     2. Set environment variable SIMPLEWORDS_TOKEN on your computer to the bot's Token.
#           Unix/Mac:      export SIMPLEWORDS_TOKEN=MzABCDefghIJKLmnopQRSTuv.EnZ3kg.b5bdD74CKCr3du679hkemGJ7R7N
#           PowerShell:    $env:SIMPLEWORDS_TOKEN='MzABCDefghIJKLmnopQRSTuv.EnZ3kg.b5bdD74CKCr3du679hkemGJ7R7N'
#
#     3. Invite the bot to your server: https://stackoverflow.com/a/37743722/257418
