Beginner needing help

Hello - kinda new to knitting. Can anyone explain this to me? I casted on 67 sts and now the pattern says " row 1&3 (WS) purl. What do they mean by WS? I realize that this means wrong side, but does that mean just to purl these rows?
thanks!

[color=indigo]Just purl the rows. Telling you it’s the ws is a piece of information that may come in handy later on…[/color]

Hi Jtravis,

I am a new knitter too, and usually put a tiny safety pin on my RS (right side) because I get lost all the time.
