Not that great at Code. how can I make one advert show a multi line advert?

Line 1\nLine 2\nLine 3

Can you show an example of merging this into 1 advert? 

"Join our Discord, Type /discord",
"Next Wipe? Type /wipe",

Available commands:
/discord
/wipe

And I will add more later but ya. That would be a great help!  Thanks! 

Available commands:\n/discord\n/wipe

You are a god! Thank you!
