Now we have to install SPI-Py using the folowing commands:

cd ~
git clone https://github.com/lthiery/SPI-Py.git
cd SPI-Py/
sudo python setup.py install

Install MFRC522-python

Almost done, just a few commands left to install this package:

cd ~
git clone https://github.com/tsndr/MFRC522-python.git
cd MFRC522-python/

Everything set up, now you can start reading and writing RFID-Tags 😉
