Reddit user metr0punk released a one-page Q-learning note (neatrl.com) as part of their RL learning journey. It covers the essentials concisely: Q-learning as an off-policy, model-free, value-based tabular method, with code snippets, the required math explained, and why it suits finite-state environments like a 9x9 grid. Includes an interactive playground, GitHub source and PyPI package — a compact starting point for RL beginners.
