[Debate] Documentation organization

### Summary

This issue is meant to be used as discussion point to define the documentation organization hosted at: https://andino.readthedocs.io/en/latest/package_summary/andino_description.html

No matter what we have right now, or what docs we have in the repositories. Let's think the best way we could provide the docs to users. (Mostly to new ones).
Let's think what we want to have online, later on we see how we adapt the current packages' info
