I am extremely new to freelancing and I'm not even sure I know what the whole thing entails. I want to work from home but I know there's more to being a freelancer. Help?
Freelancing is not a job in itself. It means being self-employed. On Upwork, the work is mostly done online (from home). You still need to offer services to clients.
You can look at the Academy classes to get started, but first step would be to see what marketable skills/experience you have that can be a service offered to clients.
