similar to e.g. python or nodejs documentation such that users can navigate the various topics of neume and that they can look up functionality etc.
Hard requirement: We should make absolutely sure that this kind of documentation isn't easily going out of date with changes that we make. Ideally we can run tests on the docs. E.g. eth-fun is testing all code examples and that's great: https://github.com/rugpullindex/eth-fun/blob/master/test/readme_test.js
So e.g. a jsdoc style documentation that is generated from natspec comments would make sense
