• code is in a uniquely-named feature branch and has no merge conflicts
• PR is descriptively titled
• ask @publiclab/is-reviewers for help, in a comment below
• Insert-step functionality is working correct as expected.

We're happy to help you get this ready -- don't be afraid to ask for help, and don't be discouraged if your tests fail at first!
