+# Utilities
+
+- _Registry_: The `Monolog\Registry` class lets you configure global loggers that you
+ can then statically access from anywhere. It is not really a best practice but can
+ help in some older codebases or for ease of use.
+- _ErrorHandler_: The `Monolog\ErrorHandler` class allows you to easily register
+ a Logger instance as an exception handler, error handler or fatal error handler.
+- _ErrorLevelActivationStrategy_: Activates a FingersCrossedHandler when a certain log
+ level is reached.
+- _ChannelLevelActivationStrategy_: Activates a FingersCrossedHandler when a certain
+ log level is reached, depending on which channel received the log record.
