+On-demand logging
+=================
+
+.. versionadded:: 2017.7.0
+
+The sole purpose of this module is logging messages in the minion.
+It comes very handy when debugging complex Jinja templates, for example:
+
+.. code-block:: jinja
+
+    {%- for var in range(10) %}
+      {%- do salt["log.info"](var) -%}
+    {%- endfor %}
+
+CLI Example:
+
+.. code-block:: bash
+
+    salt '*' log.error "Please don't do that, this module is not for CLI use!"
