## Scenarios
-Precondition: <What has to be satisfied before the use case can work?, e.g. Not authenticated>
-Main success scenario: <What is the main scenario, i.e. success scenario?, e.g. Is authenticated>
-Alternative scenario: <What is the alternative scenario, i.e. simple error handling?, e.g. Wrong credentials>
-Error scenario: <What is the other alternative scenario, i.e. fatal error handling?, e.g. Authentication block because of too many failed attempts>
-Postcondition: <What has to be valid after the scenario was run?, e.g. Access to more functions>
-Non-functional Constraints:
