title: Discord.py - change the default help command
body: <p>I'm trying to change the help command to use a pagination version of help.</p>
  <p>I understand that the following line of code removes the help command entirely:</p>
  <pre><code>bot.remove_command('help')
  </code></pre>
  <p>The docs/dicord.py server offer the following example as a way to change the default help command:</p>
  <pre><code>class MyHelpCommand(commands.MinimalHelpCommand):
      def get_command_signature(self, command):
          return '{0.clean_prefix}{1.qualified_name} {1.signature}'.format(self, command)
  
  class MyCog(commands.Cog):
      def __init__(self, bot):
          self._original_help_command = bot.help_command
          bot.help_command = MyHelpCommand()
          bot.help_command.cog = self
  
      def cog_unload(self):
          self.bot.help_command = self._original_help_command
  </code></pre>
  <p>I'm still a newbie in python, and I've only been learning rewrite for about 3 days - I'm struggling to find any working examples or an explanation that doesn't lead me back to the above code. I can't work out how to implement this into my own code - so my question is, could anyone provide further explaination into how this would be implemented using cogs?</p>
