Crashing Bot  #14

Hi BeepBoopHQ,

Once I started the bot, it keeps crashing (> 8 times).

I am runnning it locally through python ./bot/app.py. And My bot is successfully configured in Slack.

May you give a hint over what might have caused the crashing? Thank you!

Also, on the README page, may you expand on this line by explain and give steps and links "When you go through the Add your App to Slack flow, you'll setup a new Bot User and give them a handle (like @python-rtmbot)."? Thank you so much!

Cheers,
Zhong
