I don’t really recommend self-teaching, as it could result in poor technique and increases the risk of injury. Have you asked your local rink if they offer lessons? It does not matter if you join a figure skating lesson, as the basics in figure skating (such as crossovers and skating backwards) are used in hockey. You may wish to join a figure skating lesson in order to complete basics and then move on to hockey lessons. I suggest practicing your forward and backward crossovers, backward skating, forward slaloms and perhaps the basic hockey glide. I also recommend you to learn a snowplow stop/T-stop so you know how to stop. Once you’ve mastered these, you can learn a hockey stop. If you YouTube search some basic elements, including the ones I mentioned just before, there should be tutorials on how to perform these moves. :) Just remember that self-teaching could possibly result in poor technique, so I highly encourage you to see if your rink offers lessons.
Happy skating~! <3
