+# Modelina Scala Runtime project
+
+This is the Modelina Scala runtime project that is used to test the Scala-generated code from Modelina at runtime to ensure that everything works as expected.
+
+Here is how it works:
+- The models are first generated during the build phase of the project, by running the root npm script `npm run generate:runtime:scala`. These models are pre-defined with the [generic input](../generic-input.json).
+- The tests are manually added and changed.
+- When the project is tested, it tests the generated models at runtime for semantic errors.
