When the tutorial is over, you'll find that there is no guide around this rank at this point. All you have to do is just gather and wait for construction or workshops to finish to give you an island experience. This will be just relaxing, gathering, and grinding content, which I love. Always check your crafting log for new tools if you get stuck. Sometimes they show up there, and you can miss them or buildings if they can be upgraded. You get new expansion tools around rank seven.
