+// This example demonstrates how to set up a simple Scala webserver
+// implementing the popular Todo-MVC demo application. It uses the
+// Cask web framework to handle HTTP requests and Scalasql to interact
+// with an in-memory H2 database. It includes a test suite
+// that spins up the web server locally, creates a postgres testcontainer
+// and makes HTTP requests against it.
