Here lies my beautiful ASCII art of the Purplet logo. 
Dave does not approve of it, regardless of the beauty that it undeniably is.
Thus, I have no other choice but to comment it out and not add publish it,
So whereas this work of art is not going to ship with the create-purplet CLI,
it will forever remain deep in our hearts (and in the commit history and in the source code)

RIP Purplet ASCII logo
2022 - 2022

  Before you can run your bot, you need to create an ${c.cyanBright('.env')} file with a Discord
  bot token, which can be created at ${c.magentaBright(
    'https://discord.com/developers/applications'
  )}.
  Your ${c.cyanBright('.env')} file should look something like this:

    ${c.cyanBright('DISCORD_TOKEN')}=${c.grey('<your bot token>')}

  Once that is setup, you can start developing your bot by running:

    ${c.whiteBright('$')} ${c.cyanBright(packageManager)} ${c.greenBright(
  `${packageManager === 'npm' ? 'run ' : ''}dev`
)}
