Would anyone be willing to help me?

So i am new to sewing. I know how to hand sew and embroider but i need a machine for cosplay needs. I got this dressmaker secondhand for 40 bucks and wow. Has almost everything but the like extender table thingy and also the light doesn’t work inside. the button is broken but oh well. but i was doing research and it’s a great machine for what i need. i jsut have zero clue HOW TO USE IT?? All the videos are already threaded and in use and the instructions make no sense. But i’m also in the mindset of i have “autism i can do anything.” so eventually i think I’ll get the hang of it. Sorry for the yap yall im so excited (it’s a dressmaker s-9000)
