Getting start with music production & FL Studio, what should I do ?

Hello, I want to start producing and composing music with FL Studio but I don't know what to do. I feel overwhelmed when I look at everything and where to start my music journey.

I can play guitar quite well but only know a little bit of music theory. I also have no idea about stuff like plugins, vst, effect or how to create a decent drum pattern.

Please give me some advise or some useful youtube channels/videos. Thanks !
