How to hook up an ice maker water supply with no plumbing experience

Connecting a new ice maker line without a pre-existing shut-off valve or prior plumbing knowledge leaves people guessing about what fittings to buy and where the water actually taps in. This uncertainty stops them from using their fridge's built-in water and ice features, or forces them to worry about wasting money on a feature they cannot set up themselves.

“There is no water valve to turn water on or off. How the heck would it connect to a fridge? Or is it some other sort of waterline? In case you can’t tell, I have no idea what I’m even asking. Just don’t want to spend extra money on a fridge with ice and water dispenser if not able to use.”source ↗
