They are all listed on requirements.txt and expect python 3.5.6.
Instal with pip install -U -r requirements.txt
As django persistent storage, webxadrez/settings.py expects a PostgreSQL database. Default settings are on localhost, but environment variables can be created to direct to an external installation.
For django-channels channel-layers backend, it expects a Redis installation (default on localhost, but may be configured).
The intended deployment host is heroku (Procfile file serves this purpose)
When deploying to heroku, config/nginx.conf.erb configures an nginx server to route static/** urls to an external server configured with env variable STATIC_URL and route other urls to local server running django-channels
Currently, STATIC_URL points to an instance of google's firebase service.
Provided all dependencies listed have been met, running python manage.py runserver activates a local server on port 8000.
It does NOT make use of firebase, instead serving local files directly with the django server. Also, it does not make use of an nginx server, instead using purely django-channels dev server.
Database and package dependencies still hold, though.
