+### Automated CI Pipeline (GitHub Actions)
+This repository is configured with a GitHub Actions workflow (.github/workflows/e2e-tests.yml).
+
+On every push to the main branch, the workflow will automatically:
+
+1. Check out the latest code.
+2. Build the python-tests Docker image.
+3. Start the selenium and tests services using docker compose.
+4. Wait for the Selenium container to be "healthy" (using our healthcheck).
+5. Run the entire pytest suite inside the tests container.
+6. Report a Pass (✅) or Fail (❌) based on the test results.
+7. Upload the allure-results folder as an artifact for inspection.
