+## End-to-End Testing with Playwright
+
+The frontend includes initial end-to-end tests using Playwright. To run the tests, you need to have the Docker Compose stack running. Start the stack with the following command:
+
+```bash
+docker compose up -d
+```
+
+Then, you can run the tests with the following command:
+
+```bash
+npx playwright test
+```
+
+You can also run your tests in UI mode to see the browser and interact with it running:
+
+```bash
+npx playwright test --ui
+```
+
+To stop and remove the Docker Compose stack and clean the data created in tests, use the following command:
+
+```bash
+docker compose down -v
+```
+
+To update the tests, navigate to the tests directory and modify the existing test files or add new ones as needed.
+
+For more information on writing and running Playwright tests, refer to the official [Playwright documentation](https://playwright.dev/docs/intro).
