Hi Sparragus,
Sorry we missed you post. Once you have purchased your server, all you need to do is click the START button in the control panel to start your server. Then copy the IP / URL for your friends to join.
That's about it really!
Your friends should be able to join immediately and play.
Once you get bored of vanilla, start installing some modpacks and plugins from the control panel for unlimited fun!
If you have issues, we are always here to help from the Support section.
Happy Gaming!
