 A simple, responsive web interface to control wifi, hostapd and related services on the Raspberry Pi.
 
 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/BlackrockDigital/startbootstrap-sb-admin-2), a Bootstrap based admin theme. Since then, the project has evolved to include greater control over many aspects of a networked RPi, better security, authentication, a Quick Installer, support for themes and more. RaspAP has been featured on sites such as [Instructables](http://www.instructables.com/id/Raspberry-Pi-As-Completely-Wireless-Router/), [Adafruit](https://blog.adafruit.com/2016/06/24/raspap-wifi-configuration-portal-piday-raspberrypi-raspberry_pi/), [Raspberry Pi Weekly](https://www.raspberrypi.org/weekly/commander/) and [Awesome Raspberry Pi](https://project-awesome.org/thibmaek/awesome-raspberry-pi) and implemented in countless projects.

 ## Manual installation
 These steps apply to the latest release of Raspbian (currently [Stretch](https://www.raspberrypi.org/downloads/raspbian/)). Notes for previously released versions are provided, where applicable. Start off by installing git, lighttpd, php7, hostapd and dnsmasq. 
 ```sh
-$ sudo apt-get install git lighttpd php7.0-cgi hostapd dnsmasq
+$ sudo apt-get install git lighttpd php7.0-cgi hostapd dnsmasq vnstat
 ```
 **Note:** for Raspbian Jessie and Wheezy, replace `php7.0-cgi` with `php5-cgi`. After that, enable PHP for lighttpd and restart it for the settings to take effect.
