Raspberry Pi touchscreen setup

I recently bought 2 touch screens for the raspberry pi:

• 5 Inch HDMI TFT LCD Touch Screen For Raspberry PI 2 Model B / B+ / A+ / B
• 3.5 Inch TFT LCD Display + DIY Acrylic Case For Raspberry Pi 2/B+

OS Installation

Follow the raspbian installation instructions: Setup Raspberry PI with Raspbian

Configure for the 3.5" Touch Screen
