The platform works in such a way that you record your journeys under the "My journeys" tab. This as a driver or passenger. 

Once this happened, the system can search for matches for you and find them under "Carpool" ads. 

The starting point or destination always consists of a freely selectable address (can be your home address) and a defined Hitchhike Mittfahrpunkt address. ( Can be your place of work, petrol station etc. )
