I installed redis and hubot-redis-brain, and my hubot is connecting to redis every time it starts. But i still don't know how to save data to redis, none of the hubot info seems to be saved by redis. I haven't set up any variable either. so all i need to do is just
export REDIS_URL=redis://passwd@192.168.0.1:16379/prefix ?
that will make redis remember all the log in information? any more setup i need to do? what do i need to do to save hubot data to redis? Is there tutorial i can read ?
