+# Modern version of ExpenseReport with namespaces and PHPUnit
+
+This PHP implementation of the ExpenseReport is more compliant to current PHP
+standards (see https://www.php-fig.org/).
+
+The folder now contains a "composer.json" file for dependency management and
+the makefile contains targets to build the app (`make all` or simply `make`)
+and run the unit-tests (`make tests`).
+
+The configuration file for [PHPUnit](https://phpunit.de/) is sufficient to
+start with simple tests and provides a first simple example on how to test the
+output which is generated by the initial version of the ExpenseReport.
+
+Happy Coding!
