The only thing you have to google for is “Port Forwarding” and it’s usually a few clicks in your router interface. Then you just run the service you want on your computer / NAS / Raspberry Pi and tell your router to forward the port to your service IP / Port. If you have a dynamic IP at home you probably also do have to get a script or something to update your domain records if you want to point a domain to your home service.
