 ### Lookout::Rack::Utils::Log
-  You'll need configatron set up.  If `Lookout::Rack::Utils::Graphite` is
-present, it will increment those stats whenever a log is written.
+
+  The logger can be configured with
+
+  ```ruby
+  Lookout::Rack::Utils::Log.set_instance(my_logger)
+  ```
+
+  By default it will use a Lookout::Rack::Utils::LookoutLogger, which
+  wraps Log4R.  You'll need configatron set up.  If
+  `Lookout::Rack::Utils::Graphite` is present, it will increment those
+  stats whenever a log is written.
 
   ```ruby
   configatron.project_name = 'My project name'
   configatron.logging do |l|
     l.enabled = true
