  ## Documentation
  -- Documentation of RxJs will be shortly inline and more detailed in [rxjs-docs](https://github.com/ReactiveX/rxjs-docs)
  -- The [Documentation Guidelines](https://github.com/ReactiveX/rxjs-docs/blob/master/DOCUMENTATION_GUIDELINES.md) will support you
  -- Please keep both documents up to date
  +- The documentation is auto-generated directly from the source code.
  +- In short: From the source code we generate JSON documents, describing each operator, function ... and render this JSON within an Angular application
  +- The folder `docs-app` contains everything you need for building and developing the docs
  +- the folder `doc` used to be the documentation, but should remain until all content is transfered.
  +- The [Documentation README](docs_app/README.md) will support you
  +- After a PR is merged to master the docs will be published to https://rxjs-dev.firebaseapp.com/
