-If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely.

+## Sprint 4 – Secure API Key Management
+
+In Sprint 4, secure handling of API keys was implemented for the V2D (Video to Document) framework.
+
+### Implementation Overview
+- API keys are **not stored in the source code**
+- The backend loads the key from an **environment variable**
+- A single configuration works for all users without manual setup
+- Secrets are protected from being exposed in the repository or frontend
+
+### Configuration
+The backend expects the following environment variable:
+
+
+This variable is injected at runtime by the deployment or CI/CD environment and referenced in `application.yml`.
+
+### Security Benefits
+- Prevents accidental exposure of API keys
+- Ensures secure collaboration in GitLab
+- Follows best practices for secret management
