+    be used to organize larger applications.  They represent blueprints that,
+    in combination with a :class:`Flask` object are used to create a large
+    application.
+
+    A module is like an application bound to an `import_name`.  Multiple
+    modules can share the same import names, but in that case a `name` has
+    to be provided to keep them apart.  If different import names are used,
+    the rightmost part of the import name is used as name.
+
+    Here an example structure for a larger appliation::
+
+        /myapplication
+            /__init__.py
+            /views
+                /__init__.py
+                /admin.py
+                /frontend.py
+
+    The `myapplication/__init__.py` can look like this::
+
+        from flask import Flask
+        from myapplication.views.admin import admin
+        from myapplication.views.frontend import frontend
+
+        app = Flask(__name__)

+
+        from flask import Module
+
+        admin = Module(__name__)
