How to build a chat app with Ruby on Rails

I recently put together a chat build tutorial where strangers can connect with each other via advanced group chats. I wanted to run it here and see if there's any suggestion or feedback to make it better

I recently created a tutorial on building a chat application that allows strangers to connect through advanced group chats using MirrorFly’s Chat APIs and SDKs. I'd love to share it here and get your suggestions or feedback on how I can make it even better.

Thanks for your answer. This is what I'm looking for.
