The easiest way to start is to get in touch with the executive of a community hockey association and let them lead you through the process.

I was a coach in the past, although it was for my brother's team. I found that was the easiest way to get in, if you had someone related involved. We already knew all the people, because of our involvement on the players side, so it was easy to know who to talk to.
If you have specific questions, I may be able to answer some of them but things may have changed since I was a coach.
