 Deinstallation

 - run `sudo make uninstall` it will remove all created folders (also the **ffplayout.yml** configuration file!)
+
+Manual Installation
+-----
+The routine with `make` build a virtual environment with all dependencies, and install ffplayout to **/opt/ffplayout-engine**. If you do not want to install to this path, or you want to install the dependencies globally, you can do everything by hand.
+
+Just copy the project where you want to have it, run inside `pip3 install -r requirements.txt`. For logging you have to create the folder **ffplayout** under **/var/log/**, or adjust the settings in config. **ffplayout.yml** have to go to **/etc/ffplayout/**, or should stay in same folder.
+
+If you want to use the systemd service, edit the service file in **docs/ffplayout.service**, copy it to **/etc/systemd/system/** and activate it with: `sudo systemctl enable ffplayout`.
+
+Using it Without Installation
+-----
+Of course you can just run it too. Install only the dependencies from **requirements.txt** and run it with **python ffplayout.py [parameters]**.
