# Raspberry PI operating system
I'm using [Raspbian](https://www.raspberrypi.org/downloads/raspbian/) as it have full support for Raspberry PI, simple package manager and it's pretty stable

# Automatic install
1. Clone this repository on your home directory
2. Run `./install.sh`. You will be asked for your ground station lat/lon position.
3. If you want automatic Twitter posting, see: [Set your Twitter credentials](#set-your-twitter-credentials)


This is pretty much the entire setup. If you are interested about the behind of scenes please check the following section
