 ==================================
 
-.. code:: console
-

   $ testament pattern "tests/*.nim"

 To search for tests deeper in a directory, use
 
-.. code:: console
-
+  ```console
   $ testament pattern "tests/**/*.nim"    # one level deeper
   $ testament pattern "tests/**/**/*.nim" # two levels deeper
