Start with a chain of 3:

Yarn over, insert hook into first chain, and into back loop of that first chain.

Yarn over and pull through those 2 loops. (3 loops on hook) Yarn over, pull through 1 loop. (3 loops on hook)

Yarn over pull through 2 loops. (2 loops on hook) Yarn over, pull through last 2 loops

This completes your first Chain 1 and first Double Crochet

Second Foundation Double Crochet

Yarn over, insert hook into first foundation chain, making sure you pick up the loop behind it. (4 loops on hook)

Yarn over, pull through 2 loops. (3 loops on hook) Yarn over pull through 1 loop.  (3 loops on hook) Yarn over pull through 2

Yarn over, pull through last 2 loops.

Continue on until you have reached your total number of double crochets in your Row 2 Plus 1 on instructions you are following. 

For each foundation you are:

Yarn over, pull up 2 loops, pull through 2 loops, yarn over pull through 1 loop.  (Creates chain)

Yarn over, pull through 2 loops, yarn over pull through 2 loops.  (Creates double crochet)

So when you are ready to start your 2^nd row of instruction, you will turn your work so that the chains are on the bottom and you are working into the first double crochet
