The tutorial at https://wikitech.wikimedia.org/wiki/Data_Platform_Engineering/Dashboard_tutorial was previously somewhat buried under old docs, but it could contain valuable information, and having a tutorial doc is great for users.

This page should be reviewed to verify its accuracy and completeness. It was linked from the main Dashiki doc at https://wikitech.wikimedia.org/wiki/Data_Engineering/Systems/Dashiki, but the link was hard to see, so I moved it to a more obvious section under the Quickstart.
