What structure of Use Case did you use? Main sections.

The standard structure of a Use Case typically includes the following main sections:

• Title — a brief and clear name of the use case.
• Actors — who interacts with the system (users, external systems).
• Goal — what the user wants to achieve.
• Preconditions — the state of the system before the scenario begins.
• Main flow of events — the sequence of steps to achieve the goal in a normal scenario.
• Alternative flows — variations in the development of events, deviations from the main scenario.
• Postconditions — the state of the system after the scenario is completed.
• Exceptions — handling errors and exceptional situations.

This structure helps clearly describe functionality from the user's perspective and system interaction.
