What are they telling me to do on the crochet pattern?

Close Top of Hat: Last round worked is top of hat. Hook is currently at top, back center of hat. Keeping loop on hook, insert hook into top, center front of hat, yarn over and draw up a loop, yarn over and draw through 2 loops on hook (sc complete). Pinch side edges to the same center point and sc the edges together (by inserting hook through both thicknesses and completing an sc). The top of the hat will now be in a star formation. Continue to pinch opposite edges and sc them together until top of hat is completely closed. Fasten off.
