Sue, perhaps you were thinking of NexStitch?
A chain looks like a string of “V” shapes on the top and a ridge of purl bumps on the bottom or back. ( see http://www.fiber-images.com/Free_Things/How_Tos/free_how_to_crochet.html#FoundationRow )
Don’t count the loop on the hook nor the slip knot.
Below the “O” is the loop on the hook. There are four chain stitches and the * is the knot and / the tail.
Most of the time you count moving away from the hook.
With a chain 4 you can DC in the 4th chain from the hook, then DC in the same chain 5 more times and join with a slip stitch. This is one way to start crochet in the round for doily or Amigurumi.
One great thing about crochet is how versatile it can be. Where you put you hook into a starting chain is actually a small variation so long as you are consistent.
The above image is from www.fiber-images.com page on How to Crochet which has some clear drawings on foundation chains and also where to insert your hook.
When you have loosely crocheted your foundation chain. The next step is to follow their link to “Chart for Crochet Turning Chains.”
If you get your crochet pattern from the Internet, please note that outside the USA crochet stitch names change.
