+    <p>EGF is an engine based on four types of generation unit:
         <ul>
-            <li><a ref="http://wiki.eclipse.org/EGF/Portfolio/EMF">Enhanced EMF Generation</a>: 1) it enriches the EMF generation with new generation topics (e.g., html doc, ecoretools diagrams, Java doc), 2) it opens the EMF Generation customization with the EGF patterns</li>
-            <li><a ref="http://wiki.eclipse.org/EGF/Portfolio/Build">Build chain editor and generator</a>: it provides 1) an editor to model a build chain for continuous integration, and 2) a generator with targets, by default, Hudson/jenkins and Buckminster</li>
+            <li>Task: it enables to execute code written in a language (e.g., Java, Ant, JRuby) and tools (e.g., Acceleo, ATL, Jet)</li>
+            <li>Factory component: it declares generation parameters and orchestrates calls to tasks or other factory components</li>
+            <li>Pattern: it is a powerful formalism which enables to process resources (e.g., model, file), in a language (e.g., Java, Jet), with parameters (e.g., navigation strategy, post-processor, reporter)</li>
+            <li>Generation Chain: it is a domain-specific model which enables to abstract generations</li>
         </ul>
+	EGF focuses is more than a generation tool. It is a tool of generative technique. For instance, to generate a software application, EGF can invoke model or text-to-text transformation engines.

-	<h3>Activity Workflow</h3>
-	<p>The EGF infrastructure does not strictly reduce EGF to generation. 
-	Software production includes related generation activities, such as the creation of the generation environment. 
-	As a consequence, EGF can just be used for its <b>activity workflow</b> 
-	(contained in a factory component) 
-	which enables to combine activities written in one or several different languages. Java and Ruby are the two languages supported today.</p>
