This is a sample Slack Button application that provides a custom
Slash command.

This bot demonstrates many of the core features of Botkit:

*
* Authenticate users with Slack using OAuth
* Receive messages using the slash_command event
* Reply to Slash command both publicly and privately

# RUN THE BOT:

  Create a Slack app. Make sure to configure at least one Slash command!

    -> https://api.slack.com/applications/new

  Run your bot from the command line:

    clientId=<my client id> clientSecret=<my client secret> port=3000 node bot.js

    Note: you can test your oauth authentication locally, but to use Slash commands
    in Slack, the app must be hosted at a publicly reachable IP or host.


# EXTEND THE BOT:

  Botkit has many features for building cool and useful bots!
