Sorry but I can't read it, the resolution is blurry. But hey! I just got into water adjustment myself this week and can certainly feel your confusion/apprehension etc...
I Googled Bru'n Water and the spreadsheet shows up 1st from this link
2nd on that search is this YouTube video that walks you through entering your water report
I spent hours on this the first time through it. It get's easier during the 2nd and 3rd recipe you enter... but water is the biggest hurdle I have experienced in home brewing to date.
