+# Compliance checks
+
+This folder contains a python script to ensure compliance with very basic naming conventions.
+
+You can either run the script over all folders likes this:
+````
+python scan_tf.py
+````
+
+Or you can check a specific folder like this (fully qualified path needed):
+````
+python scan_tf.py /workspaces/btp-terraform-samples/released/discovery_center/mission_3680
+````
+
+As a result the script will tell you if there are some deviations from the naming conventions.
