+Logging from Spiders
+====================
+
+The recommended way for logging from spiders is to use the Spider ``log()``
+method, which already populates the :func:`~scrapy.log.msg` ``domain``
+argument. The other arguments of the Spider ``log()`` method are the same as
+the :func:`~scrapy.log.msg` function.
