Fix docs: "Getting Started" and "Tutorials"

There were several intentional breaking changes in the API
which are now included in v0.18.0 release.

This commit mostly focuses on updating the documentation to
reflect API changes. This includes making sure that snippets
and example outputs match the current state of the project.

Relevant PRs:
* #1439
* #1434
