+===================
+Configuration files
+===================
+
+SemanticScuttle uses at least two configuration files:
+
+1. Default configuration file ``config.default.php``
+2. Custom configuration file ``config.php``
+
+
+The **default configuration** file contains sensible defaults for most users
+that do not need to be changed to get started.
+
+Never change it - it will get overwritten with the next update.
+If you want to change values in it, copy them into your personal
+``config.php`` file - updates to SemanticScuttle will not change that one.
+
+The **custom configuration** file, ``config.php`` is created by copying the
+shipped ``config.php.dist`` file and modifying the values in there.
+
+It consists of the configuration directives that should be set on every
+fresh installation.
+
+
+
+Configuration scenarios
+=======================
+
+Simple installation
+-------------------
+Put your configuration file in ``data/config.php``.
+If you installed SemanticScuttle's PEAR package, use::
+
+    $ pear config-get data_dir
+    /usr/share/php/data
+
+to find the data directory location and append ``SemanticScuttle/`` to it.
+In this case, the configuration file has to be in::
+
+    /usr/share/php/data/SemanticScuttle/config.php
+
+
+The configuration file may also be saved into::
+
+    /etc/semanticscuttle/config.php
+
+
+Multiple SemanticScuttle instances
+----------------------------------
+The files of one single SemanticScuttle installation may be shared
+for several SemanticScuttle instances.
+
+To be able to configure them differently, SemanticScuttle supports
+per-host configuration files:
+
+- ``data/config.$hostname.php``
+- ``/etc/semanticscuttle/config.$hostname.php``
+
