How to set player spawn point in minecraft?

Can someone tell me how to set a fixed spawn point in a map world that I have created and downloaded to planet minecraft like when someone downloads my map they can spawn to a certain area when the map is first loaded. With out using beds or any mods

The command is /setspawn

It should say *Spawn Set*

The way to test this is by doing "/spawn"

Make sure you have essentials!

Have a good one!
