Symbols in a pattern

I was looking at the patterns on this site and I found the one for the knitted peace sign, I printed off the pattern and looked at what the different symbols meant, however the peace sign is maked with blank squares, what should I do? Should I just knit? :thinking:

It looks like all the squares are given symbols except for the ones that actually make up the peace sign, and judging by the picture Iā€™d say that those stitches are knit on the right side and purled on the wrong side.
