I want to start selling stuff online but I literally don't know anything help?

Hey everyone,

So I keep hearing about people making money with online stores and I really want to try this but I'm gonna be honest like I have NO idea what I'm doing

Like I don't even really know what ecommerce means exactly or how any of this works. Do I need to buy products firstif so WHERE? Do I need a warehouse? How does the money part even work?

I'm seeing all these terms like ecomerce and Shop and I'm just confused. Where do I even start learning this stuff? Is there like a basics for dummies guide somewhere?

I'm not looking to get rich quick or anything, I just genuinely want to learn how to do this from the ground up. But right now I'm so lost I don't even know what questions to ask.

Can someone just explain to me in simple terms: What is this actually? How do I get started? Where do I learn the basics? Is this something a complete beginner can actually do?

Any help would be amazing because right now I'm just scrolling through posts here and half the stuff doesn't even make sense to me yet.

Thanks
