• Download and install node.js.
• Install postgresql and have a database running.
• Clone the project in a folder somewhere.
• edit pg_init.py to match your own config (by default it has 2 players, MMR of 25 and sigma of 8.33)
• Open the terminal on the folder where the project is.
• run npm install once.
• run python pg_init.py WARNING! every time you execute this previous command, the database will be DROPPED. Don't do that on the production server.
• run node server.js to start the server.

The web pages are served by Express running on NodeJS. The entire project is built to be deployed on Heroku.

Create/edit a .env file at the root of the project, containing the PostgreSQL and plotly config info:

PG_HOST="localhost"
PG_USER="user"
PG_PASSWORD="password"
PG_DB="tagpro"
PG_PORT=5432
plotly_api_key="valid plotly key"
plotly_username="your plotly username"

You can also add usernames and password for the simple-auth : USERNAME, PASSWORD, USERNAME_2, PASSWORD_2 (up to 5)

Static resources (HTML pages, css, scripts, images) can be found in /public.

A Python script will compute the new rankings after each match.

Another Python script will plot the players' rankings through plotly.
