iD editor walkthrough

The walkthrough of iD editor gives instructions on how to use iD, and to give you an opportunity to practice basic tasks without modifying actual OpenStreetMap data.
When you first start the iD editor, you will be prompted with the option to start mapping or try the walkthrough. If it does not ask you at the start, then you can launch the walkthrough from iD's help button on the right-hand side, see the screenshot on this page.
The iD editor has a built-in walkthrough and after version 2.4.0 of iD some new changeset tags such as changesets_count=* were added to the changesets of users that have less than 100 edits.[1][2]

History
The walkthrough was introduced in 2013. [1] It is set in Three Rivers, Michigan, a small town in the Midwestern United States. Three Rivers was selected for having reasonable coverage without overwhelming new users with micromapping. [2]
The content was overhauled in 2014 based on a usability study [3] and again in 2017. [4] In 2018, two State of the Map U.S. 2018 attendees took a road trip out to Three Rivers to collect street-level imagery for Mapillary to use in the walkthrough.
