 This project was inspired by a [**blog post**](http://sirlagz.net/2013/02/06/script-web-configuration-page-for-raspberry-pi/) by SirLagz about using a web page rather than ssh to configure wifi and hostapd settings on the Raspberry Pi. I mostly just prettified the UI by wrapping it in [**SB Admin 2**](https://github.com/IronSummitMedia/startbootstrap-sb-admin-2), a Bootstrap based admin theme :smile:

 ## Prerequisites
 You need to install some extra software in order for the Raspberry Pi to act as a WiFi router and access point. If all you're interested in is configuring your RPi as a client on an existing WiFi network, you can skip this step. 
 
 There are many guides available to help you select a WiFi adapter, install a compatible driver, configure HostAPD and so on. The details are outside the scope of this project, although I've had consistently good results with the [**Edimax Wireless 802.11b/g/n nano USB adapter**](http://www.edimax.com/edimax/merchandise/merchandise_detail/data/edimax/global/wireless_adapters_n150/ew-7811un) – it's small, cheap and easy to work with.

+## Optional services
+OpenVPN and TOR are two additional services that run perfectly well on the RPi, and are a nice way to extend the usefulness of your WiFi router. I've started on interfaces to administer these services. Not everyone will need them, so for the moment they are disabled by default. You can enable them by changing these options in `index.php`:
+
+```sh
+// Optional services, set to true to enable.
+define('RASPI_OPENVPN_ENABLED', false );
+define('RASPI_TORPROXY_ENABLED', false );
+```
+Please note that these are simply UI's only for now. If there's enough demand I'll complete the funtionality for these optional admin screens.
