How do Tutorials Work?
Tutorials begin with a JSON configuration object stored in the TutorialConfig model. This config can be easily viewed/edited on: https://www.powr.io/tutorial_configs
A preview of the tutorial is shown on each tutorial_configs/edit page.
When a user visits standalone and is in the install step and selects a platform, standard_tutorial.jsx makes an ajax call to auto_docs#tutorial_config which pull the relevant tutorial_config and then renders the tutorial.
