Setting Up

If Cache isn't in your server, you can add it here

Once you've invited cache, make sure it has administrator permissions.

Prefix

You can set a prefix for the bot, mentioning it also works as a prefix

!set_prefix <new prefix>

Word Prefixes

Sometimes a ! or a ? doesn't do it for you and you want a prefix like Hi, to prevent you having to do hihelp you can set the prefix like this

!set_prefix "<new prefix> "

The qoutation marks are important as they tell the bot that the string has ended, now you can do <new prefix> help with a space
