Roadmap needed

[nbro]

This project seems to be a good starting point for a good RL library.

However, it doesn't seem to have a roadmap and it wouldn't be easy for other people to understand what features should or not be implemented, and why.

If I wanted to contribute to this project, I wouldn't know how to start. Yes, sure, I can look at the code and maybe try to implement some feature, but who knows if you would accept this pull request. It would quite be a waste of time. This project seems to have started as a personal project, but it could become a good library for RL and compete with other RL libraries (like stable-baselines).

Here are some of the questions that the ROADMAP could/should answer.

• What is the ultimate goal of this library?
• What features do we really want to support?
• How do we decide whether a feature is worth implementing or not? Should we use a voting mechanism?
• What features have already been implemented?
• What are the short and long-term goals?
• How do we organize the efforts?
• How about the DevOps part?
  • Should all features be tested before being released?
  • How about the versions of the crate? How do you handle them? What about stability?
  • Should we use branches when introducing a new feature?
