-# Rummy
-
-A modular Python implementation of the classic Rummy card game - but to be played by *agents* :)
-
-### Quick start (using uv)
-
-All startup, installs and test runs should use the provided uv environment wrapper from this directory.
-
-1. Open a shell in the repository root and change into the RUMMY folder:
-
-    cd RUMMY
-
-2. Run tests and install dev deps (example):
-
-    uv run python3 -m pip install --upgrade pip
-    uv run python3 -m pip install pytest
-    uv run python3 -m pytest -q
-
-3. Run the example entrypoint (small simulation):
-
-    uv run python3 Rummy.py
-
-Package usage (importing in code)
-
-- From your Python code you can import the environment and game directly:
-
-    from rummy.env import RummyEnv
-    from rummy.game import RummyGame
-
-- Create an environment and reset to get the first observation:
-
-    env = RummyEnv(["Alice", "Bob"], seed=42)
-    obs = env.reset()
-
-Testing and CI
-
-- The repository contains unit tests under `tests/` that validate deck size, dealing, and meld/sequence validation.
-- A GitHub Actions workflow at `.github/workflows/python-app.yml` runs the tests on push and pull requests.
-
-Challenge notes
-
-This repo is intended as a small challenge: some rules and edge cases are intentionally simplified and there are three suggested issues for contributors to improve:
-
-- Fix winner detection and game-end flow
-- Improve meld and wildcard validation rules
-- Expand the RL observation/action API for agents
-
-Contributing
-
-- Open a PR with targeted changes and include/adjust tests to cover the change.
-- The CI workflow will run the test-suite automatically.
-
-License
-
-- This project is provided as-is for educational and challenge purposes. Add a license file if you want to publish it.
