+## Errors and Exceptions
+
+All errors and exceptions are caught by Flight and passed to the `error` method.
+The default behavior is to send a generic HTTP `500 Internal Server Error` response with some error information.
+You can override this behavior for your own needs:
+
+    Flight::map('error', function(){
+        // Handle error
+    });
+
+By default errors are not logged to the web server. You can enable this by changing the config:
+
+    Flight::set('flight.log_errors', true);
+
+## Not Found
+
+When a URL can't be found, Flight calls the `notFound` method. The default behavior is to
+send an HTTP `404 Not Found` response with a simple message. You can override this behavior for your own needs:
+
+    Flight::map('notFound', function(){
+        // Handle not found
+    });
+
+# Redirects 
+
+You can redirect the current request by using the `redirect` method and passing in a new URL:
+
+    Flight::redirect('/new/location');
