Adding Chat on my Ionic App

Hello World!!
I have been working with my ionic app, and I wanted to include a simple chat on it, but I dunno where to start.
What would be best for me to do and what will I use?

There are several tutorials in blogs on the web. The one I’m most familiar with is the one Josh Morony posted, and included in his book. It’s a good place to start.

I don’t understand your question. The ones relating to chat. Am I missing something?
