Help with charts

I am completely new to knitting with charts - when the instructions say to “work in pattern” on WS rows and there is no pattern shown on the charts for WS rows - does that mean that you are repeating the first row only backwards???

Thanks for your help!

It means to knit the knits and purl the purls as they face you. So if there is a purl on your left needle next, purl it. If there is a knit, knit it.
