@@ -10,6 +10,34 @@ OOo Template
   Rendering consists in replacing content.xml of the original OOo document
   with the content.xml generated by the OOo Template.
 
+  Special tags for including content:
+
+    - <office:include>
+        Allow you to include another document in the current template (as an OLE attachment)
+        You must specify at least the path (can be either a single name or a path name using "/")
+        and the type of the document (generally calc or writer), the default is zope's content-type.
+        The size is always specified in centimeters (with attached "cm" suffix or not).
+        You can specify the style (defined in the sylesheet) with the "style" option.
+        You can also pass "x" and "y" attributes for positioning, it's mainly useful for draw documents.
+
+       Example:
+           <office:include type="calc" width="10.100cm" height="16.000cm" path="agenda" />
+           <office:include width="15" height="20" path="/reports/my_report" />
+           <office:include path="foo" />
+
+    - <office:include_img>
+        Not unlike <office:include>, allows you to include a picture document, refer to
+        the <office:include> part for details.
+        The optional "type" attribute specifies the picture format ; you can either
+        pass a full value ("image/jpeg") or the short version ("jpeg").
+        You can also pass position parameters with "x" and "y" attributes.
+        The maxwidth and maxheight parameters are useful to set constraints.
+        The aspect ratio information try to be kept (if you set only one size
+        or if a constraint is applied).
+
+       Example:
+           <office:include x="5cm" y="1cm" path="foo" />
+
   Tips:
 
     - it is possible to embed images by calling oo_builder.addImage(image)
