 ### Testing
 
-To run the application in a test environment, you can use an embedded H2 database. This is useful for development and testing purposes.
+You can run the application in test mode without setting up a database or authentication. In this mode, any page of
+the app is available to any user without a login.
 
-To build the project and run the application with the embedded H2 database, use the following commands:
+The result data will be stored in an in-memory H2 database. You can change the test data by modifying the `data.sql` file
+or just delete it for a clean slate.
+
+To start the application in test mode, run:
 
 ```sh
-mvn clean package
 mvn spring-boot:run -Ptest
 ```
 
+The app can then be accessed at `http://localhost:8080`.

 ### Production
 
-The application requires a database to store the data. If MariaDB is already installed, make sure the database and
-credentials are correctly configured in `application-prod.properties` and skip to step [Build the project](#build-the-project).
+In production mode, the application requires an external database to store the data. If MariaDB is already installed, make sure the
+credentials are correctly configured in `application-prod.properties` and the database conforms to the schema given in `schema.sql`.
