+    from flask.ext.mako import MakoTemplates, render_template
+    from plim import preprocessor
+
+    app = Flask(__name__)
+    mako = MakoTemplates(app)
+    app.config['MAKO_PREPROCESSOR'] = preprocessor
+

+        return render_template('hello.html', name='mako')
+
+    if __name__ == "__main__":
+        app.run(debug=True)
