Being able to find answers to commonly asked questions instead of making demands on people's time by asking is a huge part of maturity. It's very common for Discord servers to have a self-serve faq/resources channel. It's rude to ask questions that can be answered there.
In this situation I find the best thing to do is to link to the resource that answers the question. A 'teach how to fish' approach. If a question is often asked that isn't answered in documentation then I enhance the documentation.
