Breaking it down, there isn't a lot to it:
Half Double Crochet
Double Triple Crochet
7 stitches, which when combined, can take the visually simple to eye-popping stunning.
So those are the stitches.
These are the techniques:
Working from side to side.
Working in the round.
Lastly, there are the turning chains:
1 for single crochet, 2 for half double crochet, 3 for double crochet, 4 for triple and 5 for double triple.
Turning chains at the beginning of each row or round in order to create the proper height for the stitch that is being utilized.
In putting that together, you learn how to thread the yarn through your hand, and how to comfortably hold your hook while executing the stitches.
Once you learn how to execute the stitches, and what they are called, you don't have a whole lot to worry about because you are going to follow a written pattern that contains all that information. A pattern tells you what yarn to use, the proper hook size, how many chains to start with, what stitches to use, what combination of stitches (if combos are used), and where to put them.
These are the basics -- don't be intimidated.
