BEGINNERS-Part 1, Group #3-Making your first row,  hold hook with right hand & bring yarn from "ball of yarn" over the top of hook with your left hand(it will be closest to hook) .  Pull loop through the one already on the hook & slightly tighten. It is your first "chain stitch."  Keep doing that until it's as long as you want, for your project.  I have some suggestions on the length in project notes on blog.

Double Crochet-(start 2nd row) Put the hook into the loop that is 2nd from the hook, wrap yarn from ball around hook, as shown above(you dont see my left hand holding, as I am snapping pic.)  Pull it through the loop. Wrap yarn from ball around hook again & pull it through the 2 hooks on hook. (See next section called, Double Crochet for picture & look for blog project to see more)
