+## Make the model play RS-Wordle alone!
+It is possible to make the model play the Rootstrap version of Wordle. To do that, you need to:
+
+* Have a Rootstrap mail account
+* Get access to the Firebase database of the RS-Wordle instance and a private key obtained from the Service accounts Project Setting. This is for authentication and has to be stored as a JSON file.
+* Use a pre-trained model that will play the game.
+
+Then, you need to create a .env file in the project root with the following properties:
+
+```
+RS_FIREBASE_CREDENTIALS_PATH=path/to/private_key.json
+RS_WORDLE_USER=rootstrap_mail_user
+RS_WORDLE_URL=rs_wordle_instance_url
+RS_WORDLE_MODEL_NAME=pretrained_model_path
+RS_WORDLE_PASSWORD=rootstrap_mail_password
+```
+
+Using [Selenium](https://www.selenium.dev/), the program simulates user interaction with the browser and makes the model play the game, retrieving the result of each attempt from the Firebase database.
+To start the fun, navigate to the project root in your terminal and execute:
+
+`python -m rs_wordle_player.rs_wordle_player`
+
 ## Branches
 There are three different working branches on the project, each one with a different representation of the state of the game
