A kinda advanced custom "help" command for your Discord.py Rewrite bots!

helpcommand.py

"""This custom help command is a perfect replacement for the default one on any Discord Bot written in Discord.py Rewrite!
However, you must put "bot.remove_command('help')" in your bot, and the command must be in a cog for it to work.

Any help please?

put this at the end of your help cog

def setup(yourbotname):
        yourbotname.add_cog(yourclassname(yourbotname))

and change "yourbotname" to your bot name , "yourclassname" to your class name

I had figured that out, but thanks anyway!

Okay i keep getting 'help' command is not found in my terminal while running it. Other than that no issues though. please help

@bsod2528 you need to add :
def setup(bot):
bot.add_cog(Help(bot))
