How to get Mee6 Custom Commands on Discord!

so i'm not sure if you know how to do this but lets say i wanted to add like a command for example, !hug @user and text pops up"@user has hugged @user!" how would i be able to do that?

for example if i want a command to be !kick (user) how do I make the bot kick that person?

But how do I get rid of the exclamation mark

Noice video mate! Btw can u make a tutorials about coding a discord bot?
