 This TYPO3 extension is an example for writing unit tests for extbase
 extensions for TYPO3 CMS using PHPUnit.
 
+The functional tests for the Repositories provide an example of creating
+records using the PHPUnit extension testing framework.
+
 The functional test for the Utility/FileUtility class provides examples
 for working with [vfsStream](https://github.com/mikey179/vfsStream/).
