 ## Manually reporting exceptions and messages
 
 To report a caught exception to Ratchet, simply call `Ratchetio.report_exception`:
 
-    begin
-      foo = bar
-    rescue Exception => e
-      Ratchetio.report_exception(e)
-    end
+```ruby
+begin
+  foo = bar
+rescue Exception => e
+  Ratchetio.report_exception(e)
+end
+```
 
 If you're reporting an exception in the context of a request and are in a controller, you can pass along the same request and person context as the global exception handler, like so:
 
-    begin
-      foo = bar
-    rescue Exception => e
-      Ratchetio.report_exception(e, ratchetio_request_data, ratchetio_person_data)
-    end
+```ruby
+begin
+  foo = bar
+rescue Exception => e
+  Ratchetio.report_exception(e, ratchetio_request_data, ratchetio_person_data)
+end
+```
 
 You can also log individual messages:
 
-    # logs at the 'warning' level. all levels: debug, info, warning, error, critical
-    Ratchetio.report_message("Unexpected input", "warning")
+```ruby
+# logs at the 'warning' level. all levels: debug, info, warning, error, critical
+Ratchetio.report_message("Unexpected input", "warning")
 
-    # default level is "info"
-    Ratchetio.report_message("Login successful")
+# default level is "info"
+Ratchetio.report_message("Login successful")
 
-    # can also include additional data as a hash in the final param
-    Ratchetio.report_message("Login successful", "info", :user => @user)
+# can also include additional data as a hash in the final param
+Ratchetio.report_message("Login successful", "info", :user => @user)
+```
 
 
 ## Person tracking
 
 Ratchet will send information about the current user (called a "person" in Ratchet parlance) along with each error report, when available. This works by trying the `current_user` and `current_member` controller methods. The return value should be an object with an `id` property and, optionally, `username` and `email` properties.

+## Exception level filters
+
+By default, all exceptions reported through `Ratchetio.report_exception()` are reporeted at the "error" level, except for the following, which are reported at "warning" level:
+
+- ActiveRecord::RecordNotFound
+- AbstractController::ActionNotFound
+- ActionController::RoutingError
+
+If you'd like to customize this list, see the example code in `config/initializers/ratchetio.rb`. Supported levels: "critical", "error", "warning", "info", "debug".
