Pattern problem please help

I am a beginner knitting a beanie hat my stitches have begun to decrease and my pattern now says

Rib 2 more rows as a set

I have no idea what this means please can someone explain what I should do next ??

As set: If it looks like a knit, knit it. If it looks like a purl, purl it.

Hi and welcome!
The row before this direction has “set” the position of the rib, whatever that pattern is (k1p1 or k2,p1 or whatever). Now you should continue the rib patterning, knitting the Vs and purling the bumps as GG suggests.
Can you give us a pattern link or a pattern name?
