Had no idea how to word this in a search, so I apologize if an answer already exists. I just finished building my first app. Its use is pretty intuitive, but nonetheless some basic explanation would be helpful.
I seem to remember certain apps having a landing page you only see right after signup that explain some basic functionality. Either this or perhaps its on the signup page itself. Anyways, as a beginner dev what would be the best (and hopefully not super difficult) way to communicate to the user some basic functionality. I'm not a big app consumer myself, so please tell me where the explanation should go and how I could learn to accomplish this in code.
