+RAUC Installation History and Event logging
+-------------------------------------------
+
+Even if RAUC mainly focuses on logging information to stdout or into the
+journal (when using systemd), this might be insufficient for some purposes and
+especially for keeping long-term history of what RAUC changed on the system.
+
+A common problem for example can be journal rotation. Since storage is limited
+and the journal contains a lot of other information, it needs to be rotated at
+some point.
+However, one might want to preserve the history of what RAUC installed on the
+system or when the system rebooted, went into fallback, etc. for very long or
+even the full life time of the device.
+
+Another motivation can be to have a clearly separated distinct log location
+where other system components or a service technician (that should not have
+access to the whole system) should have a look into.
+
+The RAUC 'event logging' handling targets these and other cases.
+It defines a distinct set of events that might be of interest for later
+introspection, debugging or informative output.
+
+Via RAUC's ``system.conf`` one or several loggers can be configured with
+selectable output format, event filters, and also basic log rotation is
+supported.
+
+A new logger can be registered with adding a ``log.<loggername>`` section to
+the ``system.conf``.
+
+To have e.g. an unlimited human-readable short log of the installations
+happened on the system, use::
+
+  [log.install-log]
+  filename=install.log
+  events=install
+  output-format=short
+
+Or, if you want a json-based log of all events, limited to 1M per log file and
+5 rotation files to keep, use::
+
+  [log.all-json-log]
+  filename=all-json.log
+  output-format=json
+  max-size=1M
+  max-files=5
+
+If an error occurs during logging (such as disk full or write errors), that
+logger is marked as broken and no longer used.
+An ongoing installation is **not** aborted.
+
+For a full reference of supported configuration options, see
+:ref:`logger sections reference <ref-logger-sections>`.
+
+.. note:: All events logged using the internal event logging framework will
+   also be forwarded to the default logger and thus be visible e.g. in the
+   journal (when using systemd).

+**[log.<logger>] sections**
+
+With a logger section, a *RAUC event logger* can be configured.
+The ``<logger>`` suffix determines the internal name of the logger and must be
+unique per ``system.conf``.
+
+For an overview over the event logging framework in RAUC and its purpose, have
+a look at :ref:`sec-advanced-event-log`.
+
+``filename``
+  The log file name used for logging.
+  If no absolute path is given, the location is assumed to be relative to the
+  ``data-directory``.
+  Using a relative file name without ``data-directory`` set will cause a
+  configuration error.
+
+``events``
+  Semicolon-separated list of events to log. Currently supported event types are:
+
+  * ``install`` - Logs start and end of installation
+  * ``boot`` - Logs boot information
+  * ``mark`` - Logs slot marking information
+  * ``all`` - Log all events (cannot be combined with other events)
+
+``format``
+  The output format used for the logger. Supported values are
+
+  * ``readable``: readable mutli-line output
+  * ``short``: Single-line readable output
+  * ``json``: single-line JSON output
+  * ``json-pretty``: formatted JSON output
+
+``max-size``
+  Allows to configure a basic log rotation.
+  When given, the logger's log file will be rotated before reaching
+  the size configured with ``max-size`` and renamed to ``<filename>.1``.
+  Existing rotation file names will be incremented by one.
+  The oldest file is removed.
+  To configure a maximum number of files to keep, see ``max-files``.
+  Values support common suffixes like ``K``, ``M``, ``G``, to ``T``.
+
+``max-files``
+  Configures the maximum number of files to keep per logger.
+  E.g. if set to ``3``, only ``<filename>``, ``<filename>.1`` and
+  ``<filename>.2`` will be kept during rotation.
+  Defaults to 10 if unset.
