+'''the app'''[[BR]]
+Now comes the part of understanding the app. The nox app is based on the component class, described in component.hh (found in ./src/nox/, assuming you're in your nox directory), so you must always include this file. the basic structure of an app is as followed: 
+
+{{{
+#include "component.hh"
+
+class Hub
+    : public Component
+{
+public:
+     Hub(const Context* c,
+         const xercesc::DOMNode*)
+         : Component(c) { }
+
+    void configure(const Configuration*) {
+    }
+
+    void install()
+    { }
+};
+
+REGISTER_COMPONENT(container::Simple_component_factory<Hub>, Hub);
+}}}   
+
+this is just a stripped down version of the hub code. Most nox apps can be found in ./src/nox/coreapps/. To debug, also include vlog.hh to enable log, warning and other messages. vlog.hh and other important functionalities, called "events" are in ./src/include.
+
+Events must be registered through the Disposition handler, which returns either STOP or CONTINUE, as defined in event.hh.
