 - Follow the installation steps above to create a new slack app with all of the required permissions and event subscriptions.
 - The biggest change in requirements with the new version is the move from the [Real Time Messaging API](https://api.slack.com/rtm) to the [Events API](https://api.slack.com/apis/connections/events-api) which necessitates having a publicly-accessible url that Slack can send events to. If you are unable to serve a public endpoint, you can use [ngrok](https://ngrok.com/).
 
+## Socket mode
+
+To run the bot in socket mode, go to the app's "Socket Mode" page and enable it. Then add the app level token you got to environment variables.
+
+Finally, run the bot with "-s" or "--socket" option.
