About streaming...

I want to start streaming (mostly gaming) but I don't know where to start, what to do, what to improve etc. I don't have good enough equipment for it, I don't even have a good enough pc. I'm introverted and shy, I normally don't talk much and I don't know how to fix it. I don't even have a goal like "I will be a big streamer one day", no, I'm more than okay to have a small community including people who are actually going to enjoy watching my streams and be consistent. I guess I'm just scared, I don't know. I don't have anyone to support me in this or someone who knows about this stuff to help me to begin with. So... Any tips or ideas? :')
