i am reading github Rchat hubot adapter installation instruction from https://github.com/RocketChat/hubot-rocketchat

i still couldn’t completely understand how to integrate Hubot to RChat.
All i need to do is to install Hubot and Add adapter to hubot? I am running Rchat on Digital Ocean Ubuntu 14.04 right now. What else do i need to do ?

Is there a document/tutorial that lays out all the steps in terms of how to integrate hubot to Rchat?

Thanks in advance!
