Add Sudo in VPS server

Need a concise tutorial or guide on how to add Sudo on Vps and to assign reboot and some other 3 functions. And also how to limit it to that. Just Incase the Sudo wants to do another function, it will reject.

Read some tutorials on google but got lost on the way and don’t understand. Thanks in advance.

Can help you with this
