+================
+
+The generic_cloudooo recipe helps you to deploy cloudooo services with their configuration files.
+
+
+How to use?
+-----------
+
+Here is an example of a section to add in your software.cfg :
+
+.. code-block::
+
+  [cloudooo-configuration]
+  recipe = slapos.cookbook:generic_cloudooo
+  configuration-file = ${directory:etc}/cloudooo.cfg
+  wrapper = ${directory:services}/cloudooo
+  data-directory = ${directory:srv}/cloudooo
+  ip = 0.0.0.0
+  port = 1234
+  ooo-paster = ${directory:bin}/cloudooo_paster
+  mimetype_entry_addition =
+    text/html application/pdf wkhtmltopdf
+  openoffice-port = 1235
+  ooo-binary-path = ${directory:libreoffice-bin}/program
+  environment =
+    FONTCONFIG_FILE = ${fontconfig-instance:conf-path}
+    PATH = ${binary-link:target-directory}
+  ooo-uno-path = ${directory:libreoffice-bin}/basis-link/program
+
+
+Where :
+
+- `configuration-file` is the path where the put the configuration file;
+- `wrapper` is the path where the put the final executable file;
+- `data-directory` is the folder where cloudooo would put it's temporary files;
+- `ip` and `port` is where cloudooo will listen to;
+- `ooo-paster` is the path of the program that will load cloudooo configuration
+  and start the application;
+- `mimetype_entry_addition` is additional entries to give to the default
+  mimetype registry. (see section below.) The mimetype entry list is sorted in
+  order to make the global mimetype at the bottom of the list.
+  (i.e. `* * ooo` > `text/* * ooo`)
+
+    .. code-block::
+
+        mimetype_entry_addition =
+          <input_format> <output_format> <handler>
+
+- `openoffice-port` is the port where the internal OpenOffice.org service will
+  listen to;
+- `ooo-binary-path` is the path of the openoffice service executable file;
+- `environment` are environment vars to use with the openoffice binary;
+- `ooo-uno-path` is the path where UNO library is installed.
+
