Provide more info about the bot

[SGTGunner]

Greetings,

I see that you have put a lot of effort into this bot. But a suggestion if I may.
You need to put some images in the README.md of the bot in action as this will show a potential user/contributor.

Something like https://github.com/peterthehan/discord-reaction-role-bot

Thanks,
