Dudley,
You're still a long ways from this point but there are some eyelets you need to add in the deck and in the awning support columns - there are also some cleats that you add under the awning and to the columns. You really don't find out about them until you do the rigging and they are much easier to add before you put the awning structure on. Read ahead and do them when you build the awning. It's a pain in the you know what later on.
Also, the instructions and pictures aren't very clear as to how to attach the awning posts - look ahead and you can judge where they go by the height they should be above the deck. If you add the middle and rear posts and beams first, you can put a ruler across them bow to stern to get the correct height for the forward supports. I had to pull mine off and adjust it twice.
