Issue:

When generating a README using the application, if the "Usage" field is left empty, the Gemini API generates random data instead of leaving the field blank. This behavior can lead to confusion for users who did not intend to include this section.

Expected Behavior:

The "Usage" section should be omitted or remain empty if no input is provided by the user.

Suggested Solution:

Modify the behavior of the generator to ensure that when the "Usage" field is left empty, it is either excluded from the README or left as a placeholder (e.g., "No usage instructions provided.").
