OK, I figured out the knitting

But I've been trying to teach myself to crochet forever, I figured now's a good time to start again. My MIL gave my dd a 30 second "lesson" on Christmas and I watched. It was enough for me to chain & do a single crochet off the chain (I hope I'm saying that right).
But how do I go back down the row again? Do I flip the piece upside down? Go down the opposite side of the chain? I need a visual but that site w/ the videos requires real player and it screws up my computer everytime I try it.
I'm just trying to make a potholder or something small to get used to holding the yarn & hook, yk?
Please?
