Made logging config examples more accessible.

- Show an initial example configuring the root logger to output to the console.
- Then add more logging from the `django` named logger.
- Then show the file and more complex examples.

Adjusted surrounding text for reading flow.

 is the best source of information about logging configuration dictionaries.
 However, to give you a taste of what is possible, here are several examples.
 
-First, here's a configuration which writes all logging from the
-:ref:`django-logger` logger to a local file:
+To begin, here's a small configuration that will allow you to output all log
+messages to the console:
+
+.. code-block:: python
+    :caption: settings.py
+
+    import os
+
+    LOGGING = {
+        'version': 1,
+        'disable_existing_loggers': False,
+        'handlers': {
+            'console': {
+                'class': 'logging.StreamHandler',
+            },
+        },
+        'root': {
+            'handlers': ['console'],
+            'level': 'WARNING',
+        },
+    }
+
+This configures the parent ``root`` logger to send messages with the
+``WARNING`` level and higher to the console handler. By adjusting the level to
+``INFO`` or ``DEBUG`` you can display more messages. This may be useful during
+development.
+
+Next we can add more fine-grained logging. Here's an example of how to make the
+logging system print more messages from just the :ref:`django-logger` named
+logger:
+
+.. code-block:: python
+    :caption: settings.py

+
+    LOGGING = {
+        'version': 1,
+        'disable_existing_loggers': False,

+            'console': {
+                'class': 'logging.StreamHandler',
+            },

+By default, this config sends messages from the ``django`` logger of level
+``INFO`` or higher to the console. This is the same level as Django's default
+logging config, except that the default config only displays log records when
+``DEBUG=True``. Django does not log many such ``INFO`` level messages. With
+this config, however, you can also set the environment variable
+``DJANGO_LOG_LEVEL=DEBUG`` to see all of Django's debug logging which is very
+verbose as it includes all database queries.
