 The system was developed to be used with the [skillbird-framwork](https://github.com/FAUSheppy/skillbird). If you use this framework, the program should be working without any arguments. If you need more conductibility feel free to open a pull-request or send me a message.
 
+# How to run
+You can run the leaderboard as a flask standalone (arguments overwrite *config.py* settings!):
+
+    ./server.py --skillbird-db PATH_TO_DB
+
+or with a runner like *waitress*:
+
+    /usr/bin/waitress-serve --host 127.0.0.1 --port 5002 --call 'app:createApp
+
+the *DB_PATH* is set in *config.py* in this case.
