 The ``module_defaults`` keyword can be used at the play, block, and task level. Any module arguments explicitly specified in a task will override any established default for that module argument::
 
     - block:
-        - debug:
-            msg: "a different message"
+        - name: Print a message
+          ansible.builtin.debug:
+            msg: "Different message"
       module_defaults:
-        debug:
-          msg: "a default message"
+        ansible.builtin.debug:
+          msg: "Default message"
 
 You can remove any previously established defaults for a module by specifying an empty dict::
 
-    - file:
+    - name: Create file1
+      ansible.builtin.file:
         state: touch
