 ### Wikstraktor Server
 If you want wikstraktor as a server, you need to install [flask](https://flask.palletsprojects.com/en/2.0.x/installation/) and [flask-cors](https://flask-cors.readthedocs.io/en/latest/) — to allow other domains to query —, and best practice is to do so in a [virtual environment](https://docs.python.org/3/library/venv.html#module-venv).
