title: Is there a Predis documentation?
body: <p>I was using phpredis and now I am also trying predis for my php applications, but I couldn't find a good documentation for the second one.
  There is a "How to use" in github, but I find it quite short.
  I checked the examples though and I noticed that they are using the <a href="http://redis.io/commands" rel="noreferrer">Redis commands</a> in "lower case" characters. I tried a few and it works, but I don't want to try them all to see if this is true...</p>
