• iD is a JavaScript OpenStreetMap editor.
• It's intentionally simple. It lets you do the most basic tasks while not breaking other people's data.
• It supports all popular modern desktop browsers: Chrome, Firefox, Safari, Opera, Edge, and IE11.
• iD is not yet designed for mobile browsers, but this is something we hope to add!
• Data is rendered with d3.js.

• Read the project Code of Conduct and remember to be nice to one another.
• Read up on Contributing and the code style of iD.
• See open issues in the issue tracker if you're looking for something to do.
• Translate!
• Test a prerelease version of iD:
  • Stable mirror of release branch: http://openstreetmap.us/iD/release
  • Development mirror of master branch: http://openstreetmap.us/iD/master
