## Description
**What issue are you solving (or what feature are you adding) and how
are you doing it?**
So, we need a README.md at the root of the project, to at least welcome
anyone who might be interested in the project.
It should have:
- [ ] link to the `/play` endpoint to get a `session_id` for starting up
the server.
- [ ] (basic) info about how it works
- [ ] features
- [ ] images and/or gifs showcasing the project
