I don't think that's necessary. Musing.io is an easy to use app. It's very simple: ask or answer questions, and earn for doing both.
Important question. It's not necessary. But i think if you wants any video about musing, you can search it on dtube or youtube. And if you have any question , you should join musing discord server. Here's the link= https://discord.gg/7Ztdb9z
