 ## 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. 
+Start with a clean install of the [latest release of Raspbian](https://www.raspberrypi.org/downloads/raspbian/) (currently Stretch). Raspbian Stretch Lite is recommended.
 
-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.
+1. Update Raspbian, including the kernel and firmware, followed by a reboot:
+```
+sudo apt-get update
+sudo apt-get dist-upgrade
+sudo reboot
+```
+2. Set the WiFi country in raspi-config's **Localisation Options**: `sudo raspi-config`
 
-To configure your RPi as a WiFi router, either of these resources will start you on the right track: 
-* [**How-To: Setting up a Raspberry Pi as an access point in a standalone network (Tested with Raspbian Stretch)**](https://github.com/SurferTim/documentation/blob/6bc583965254fa292a470990c40b145f553f6b34/configuration/wireless/access-point.md)
-* [**How-To: Use The Raspberry Pi As A Wireless Access Point/Router Part 1**](http://sirlagz.net/2012/08/09/how-to-use-the-raspberry-pi-as-a-wireless-access-pointrouter-part-1/)
-* [**How-To: Turn a Raspberry Pi into a WiFi router**](http://raspberrypihq.com/how-to-turn-a-raspberry-pi-into-a-wifi-router/) (uses isc-dhcp-server instead of dnsmasq)
+3. If you have an older Raspberry Pi without an onboard WiFi chipset, the [**Edimax Wireless 802.11b/g/n nano USB adapter**](https://www.edimax.com/edimax/merchandise/merchandise_detail/data/edimax/global/wireless_adapters_n150/ew-7811un) is an excellent option – it's small, cheap and has good driver support.
 
-After you complete the intial setup, you'll be able to administer these services using the web UI.
+With the prerequisites done, you can proceed with either the Quick installer or Manual installation steps below.
 
 ## Quick installer
 Install RaspAP from your RaspberryPi's shell prompt:
