+# Modelina Go Runtime Project
+
+This is the Modelina Go runtime project that is used to test the Go-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:go`. 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.
