+# About Automated Chat
+Automated chat example shows how you can receive chats when you talk to someone using Push Chat. In this example, we establish a socket connection and then send a message to pushai.eth, which is an automated chat bot that replies back.
+
+## What's the use case
+You can use this example to see the functionality of sockets and how you can respond to messages from backend (server) when a wallet messages you (or a wallet you own). Some use cases are:
+
+- Creating an automated support bot
+- Creating an AI chat bot
+
+## Install instructions
+1. Navigate to this directory from the terminal
+2. do `npm install` or `yarn install`
+3. do `yarn start`
