Hi and welcome to KnittingHelp!
Yes, a pattern link is always helpful. Are you working with double pointed needles or circulars?
Joining in the round with 4sts can be a little awkward but it's do-able. It becomes a little easier if you can cast the 4sts onto one needle and knit the next few rows back and forth without joining in the round. You can then knit the sts off: one stitch onto each of 2 needles and 2sts on the third and then join
in the round. The same thing goes if the pattern asks you to immediately increase in each stitch. Just start off knitting back and forth, increase, and then distribute sts and join in the round. The little gap at the beginning can be closed up later with the tail of the yarn.
