Knittys topi help slip stitch rib

Using smaller circular needle, work 1 inch in Slipped Stitch Rib, ending with Round 2 of patt

i cant seem to find how to do this anywhere. i get the rest of the hat (so far :biting: ) but i dont know how to do a slip stitch rib… TIA

The slip stitch rib is written out just above where it says DIRECTIONS, immediately following the photos showing the cast on method.
