+Setting up a loops Site and Utilities
+=====================================
+
+Let's do some basic set up
+
+  >>> from zope import component, interface
+  >>> from zope.traversing.api import getName
+  >>> from zope.app.testing.setup import placefulSetUp, placefulTearDown
+  >>> site = placefulSetUp(True)
+
+and build a simple loops site with a concept manager and some concepts
+(with a relation registry, a catalog, and all the type machinery - what
+in real life is done via standard ZCML setup or via local utility
+configuration):
+
+  >>> from loops.integrator.testsetup import TestSite
+  >>> t = TestSite(site)
+  >>> concepts, resources, views = t.setup()
+  >>> loopsRoot = concepts.getLoopsRoot()
+
+  >>> from loops.layout.tests import setup
+  >>> setup()
+
+
+Defining Layouts
+================
+
+  >>> from loops.layout.base import LayoutNode
+
+  >>> demo = views['demo'] = LayoutNode('Demo Root Layout')
+  >>> demo.nodeType = 'menu'
+
+
+Fin de partie
