 This is a sample Slack bot built with Botkit.

 This bot demonstrates many of the core features of Botkit:

 * Connect to Slack using the real time API
 * Receive messages based on "spoken" patterns
 * Send a message with attachments
 * Send a message via direct message (instead of in a public channel)

 # RUN THE BOT:

 Get a Bot token from Slack:

 -> http://my.slack.com/services/new/bot

 Run your bot from the command line:

 token=<MY TOKEN> serviceUri=<LUIS_SERVICE_URI>node demo_bot.js

 # USE THE BOT:

 Find your bot inside Slack to send it a direct message.

 Say: "Hello"

 The bot will reply "Hello!"

 Make sure to invite your bot into other channels using /invite @<my bot>!

 # EXTEND THE BOT:

 Botkit has many features for building cool and useful bots!
