Short rows are pretty easy. You just knit however many sts you're told to, then for the wrap, you slip the next stitch, move the yarn so that it goes between the slipped stitch and the next stitch, then move the slipped stitch back. Then knit back the way you came. The "wrap" is just your working yarn making a loop around the base of the next unknit stitch. It holds the two rows together so you avoid a hole.
IF your pattern tells you to "hide wraps" when you do finally knit the entire row, you just pick up the wrap and knit or purl it with the stitch it goes around.
Give it a try. It's easy.
