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
* Reply to messages
* Use the conversation system to ask questions
* Use the built in storage system to store and retrieve information
  for a user.

# RUN THE BOT:

  Get a Bot token from Slack:

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

  Get a Botkit Studio token from Botkit.ai:

    -> https://studio.botkit.ai/

  Run your bot from the command line:

    token=<MY SLACK TOKEN> studio_token=<MY BOTKIT STUDIO TOKEN> node bot.js

# USE THE BOT:

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

  Say: "Hello"

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

# EXTEND THE BOT:
