+- Very easy to setup.
+- No graphics processing is done on the server, keeping the CPU load low.

-Steps
+__ https://sourceforge.net/p/surrogator/
+
+=====
+Setup
+=====
+
+1. Copy ``data/surrogator.config.php.dist`` to ``data/surrogator.config.php``
+   (remove the ``.dist``)
+2. Adjust the config file to your needs
+3. (optional) Create a default image and put it into the raw folder, name it ``default.png``
+4. Setup your web server and set the document root to the ``www/`` directory.
+   Make sure you allow the ``.htaccess`` file and have ``mod_rewrite`` activated.
+5. Add DNS entries for ``_avatars._tcp`` and ``_avatars-sec._tcp``.
+   A bind config file excerpt would look like this::
+
+    _avatars._tcp.example.org.     IN SRV 0 0 80  avatars.example.org
+    _avatars-sec._tcp.example.org. IN SRV 0 0 443 avatars.example.org
+
+   This makes the avatar server ``avatars.example.org`` responsible for
+   the domain ``example.org``, on ports 80 (HTTP) and 443 (HTTPS).
+
+It is possible to use an existing domain as avatar server.
+Just copy ``avatar.php`` into its document root dir and copy the rewrite rule
+from ``.htaccess`` into the domain's ``.htaccess`` file if one exists.
+If not, copy the whole ``.htaccess`` file.
+After that, you have to point the ``$cfgFile`` path at the beginning of
+the ``avatar.php`` file to the correct location.
+
+
+=====
+Usage
 =====
 
 1. Put images in ``raw/`` folder.
    Name has to be email address + image file extension, for example
    ``foo@example.org.png``.
-2. Generate/update big square files.
-3. Generate images for each size that is defined in ``$sizes``.
+   Surrogator supports ``.png`` and ``.jpg``.
+2. Run ``php surrogator.php``.
+   The small files get generated.
+3. You will get more information with ``-v``
+4. When you run ``surrogator.php`` again, it will only generate small files
+   when the raw file is newer than the "square" file in the var folder.
+   You can force the update with ``--force``.
+
