  Clarify the project's license in the README

  Why:

  COPY-PASTE FIX

  Copy

  Add a section or line in the README, e.g., "## License\nCleanRL is licensed under [Specify License(s) here, e.g., MIT License for code, CC-BY-4.0 for documentation]. Please refer to the LICENSE file for full details."

  Emphasize 'learning' and 'quick experimentation' in the README's opening

  Why:

  CURRENT

  CleanRL is a Deep Reinforcement Learning library that provides high-quality single-file implementation with research-friendly features. The implementation is clean and simple, yet we can scale it to run thousands of experiments using AWS Batch. The highlight features of CleanRL are: * 📜 Single-file implementation * Every detail about an algorithm variant is put into a single standalone file. For example, our `ppo_atari.py` only has 340 lines of code but contains all implementation details on how PPO works with Atari games, **so it is a great reference implementation to read for folks who do not wish to read an entire modular library**.

  Add a 'Comparison to Alternatives' section in the README

  Why:

  COPY-PASTE FIX

  Copy

  Add a new section to the README, e.g., "## Comparison to Alternatives\nCleanRL differentiates itself from modular libraries like Stable Baselines3 or RLlib by offering single-file implementations. This design choice prioritizes readability and educational value, allowing users to grasp an entire algorithm's logic within one script, rather than navigating a complex framework. While other libraries excel in production-grade deployment, CleanRL focuses on providing transparent, easily modifiable, and benchmarked reference implementations for research and learning."
