+Using debug dump helper script
+------------------------------
+Since cdist stores data to local cache that can be used for debugging there
+is a helper script that dumps data from local cache.
+
+For more info see:
+
+.. code-block:: sh
+
+    debug-dump.sh -h
+
+Or from cdist git cloned directory:
