+## Friendica\Util\Logger
+
+This namespace contains the different implementations of a Logger.
+
+### Configuration guideline
+
+The following settings are possible for `logger_config`:
+-	`monolog`: A Logging framework with lots of additions (see [Monolog](https://github.com/Seldaek/monolog/)). There are just Friendica additions inside the Monolog directory
+-	[`stream`](StreamLogger.php): A small logger for files or streams
+-	[`syslog`](SyslogLogger.php): Prints the logging output into the syslog
+
+[`VoidLogger`](VoidLogger.php) is a fallback logger without any function if no debugging is enabled.
+
+[`ProfilerLogger`](ProfilerLogger.php) is a wrapper around an existing logger in case profiling is enabled for Friendica.
+Every log call will be saved to the `Profiler` with a timestamp.
+
+### Implementation guideline
+
+Each logging implementation should pe capable of printing at least the following information:
+-	An unique ID for each Request/Call
+-	The process ID (PID)
+-	A timestamp of the logging entry
+-	The critically of the log entry
+-	A log message
+-	A context of the log message (f.e which user)
+
+If possible, a Logger should extend [`AbstractFriendicaLogger`](AbstractFriendicaLogger.php), because it contains additional, Friendica specific business logic for each logging call.
+
+Using AbstractFriendicaLogger makes the logger capable of adding profiling data for each log call.
