Scoreboard Installation Instructions

[d1runberg]

It would be nice to have a README / setup instructions for the scoreboard side of things in the repo. I will see what I can do to dig in and look at it. @NPoole do you have any thoughts / willing to do so, it would be ideal, but I know you are on other things ;)
