Slipping 1st stitch
I agree with Tab. I usually slip the first stitch. You get a nice finished looking edge that way and if you are finishing a flat item like a placemat with a crochet edge it makes this much easier. I also find it easier to seam sweater pieces together if I've slipped the first stitch too.
Like Tab said the slipped stitch is the first stitch in the pattern, so knit or purl the second stitch as the pattern calls for it.
