+\paragraph{Adding a new driver configuration}
+
+Since we currently only support two different wireless drivers : Broadcom and Atheros,
+you might be interested in adding support for another driver like Ralink RT2x00,
+Texas Instruments ACX100/111.
+
+The driver specific script should be placed in \texttt{/lib/wifi/<driver>.sh} and has to
+include several functions providing :
+
+\begin{itemize}
+ \item detection of the driver presence
+ \item enabling/disabling the wifi interface(s)
+ \item configuration reading and setting
+ \item third-party programs calling (nas, supplicant)
+\end{itemize}
+
+Each driver script should append the driver to a global DRIVERS variable :
+
+\begin{verbatim}
+append DRIVERS "driver name"
+\end{verbatim}
+
+\subparagraph{scan\_driver}
+
+This function will parse the \texttt{/etc/config/wireless} and make sure there
+are no configuration incompatibilities, like enabling hidden SSIDS with ad-hoc mode
+for instance. This can be more complex if your driver supports a lof of configuration
+options. It does not enable your wireless driver to work.
+
+\subparagraph{enable\_driver}
+
+This function will enable the driver and read the configuration file to create application
+specific configuration files for the NAS or supplicant program. It will not check the
+configuration consistency.
+
+\subparagraph{disable\_driver}
+
+This function should properly shutdown the wireless interfaces and kill associated programs
+running on top of it.
+
+\subparagraph{detec\_driver}
+
+This function should reliably report the existence of the driver and of one or more of its
+wireless interfaces. A basic configuration file has to be generated in the meantime.
