# 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. Update repositories and install git
```
sudo apt update
sudo apt install git
```
2. Clone this repository on your home directory
```
cd $HOME
git clone https://github.com/reynico/raspberry-noaa.git
cd raspberry-noaa
```
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
