 RPi.GPIO is necessary to use external buttons as a trigger but it works just fine without. Triggering is then only possible using touch screen / mouse or key 'c'.

+8. Optional but highly recommended, as it improves performance significantly: install some Python bindings for gPhoto2. For that, either [Piggyphoto](https://github.com/alexdu/piggyphoto) or [gphoto2-cffi](https://github.com/jbaiter/gphoto2-cffi) can be used. At the moment, Piggyphoto doesn't allow to disable the sensor while idle, so gphoto2-cffi is preferred.
+
+   8.1 Installing gphoto2-cffi:
+   Install [cffi](https://bitbucket.org/cffi/cffi)
+   ```
+   sudo apt-get install libffi6 libffi-dev python-cffi
+   ```
+   Download and install gphoto2-cffi for gPhoto2
+   ```
+   git clone https://github.com/jbaiter/gphoto2-cffi.git
+   cd gphoto2-cffi
+   python setup.py build
+   sudo python setup.py install
+   ```
+
+   8.2 Install Piggyphoto:
+   Download [Piggyphoto](https://github.com/alexdu/piggyphoto) and put the folder `piggyphoto` into the Photobooth-directory.
 
 9. Optionally make the software run automatically on startup. To do that, you must simply add a corresponding line in the autostart file of LXDE, which can be found at `~/.config/lxsession/LXDE-pi/autostart`. Assuming you cloned the Photobooth repository into `/home/pi/photobooth`, add the following line into the autostart-file:
