+Logging Configuration
+=====================
+
+To get an idea of how the current status of an ownCloud system is or to
+solve issues log information is a good point to start with. ownCloud allows
+to configure the way how and which depth of information should be logged.
+
+Parameters
+----------
+
+  First you need to decide in which way logging should be done. You can
+  choose between the two options ``owncloud`` and ``syslog``. Then you need
+  to configure the log level which directly influences how much information
+  will be logged. You can choose between ``0=DEBUG``, ``1=INFO``, ``2=WARN``
+  and ``3=ERROR``.
+  The most detailed information will be written if ``0`` (DEBUG) is set, the
+  least information will be written if ``3`` (ERROR) is set. Keep in mind that
+  it might slow down the whole system if a too detailed logging will has been
+  configured. By default the log level is set to ``2`` (WARN).
+
+  **owncloud**
+  - All log information will be written to a separate log file which can be
+  viewed using the log menu in the admin menu of ownCloud. By default a log
+  file named ``owncloud.log`` will be created in the directory which has
+  been configured by the ``datadirectory`` parameter.
+  ::
+
+    "log_type" => "owncloud",
+    "logfile" => "owncloud.log",
+    "loglevel" => "3",
+
+  **syslog**
+  - All log information will be send to the default syslog deamon of a system.
+  ::
+
+    "log_type" => "syslog",
+    "logfile" => "",
+    "loglevel" => "3",
