+## Minimal test prodecure
+For the purposes of the Python 3 effort, a "tested" radio means
+at least the following procedure was followed:
+1. Download from the radio
+1. Make some change to a memory
+1. If the radio has settings support, make sure settings load and tweak one setting
+1. Upload to the radio
+1. Confirm that the changes stick and look correct, or at least are not a
+   regression from the master py2 branch.
+
+The drivers are all passing the automated tests, but tests with real hardware
+and serial ports is important, especially around bytes-vs-string safety.
+
+To update this document, add/edit entries in `tests/py3_driver_testers.txt` and
+then run `tox -e makesupported`. Commit the result (including the changes to this `.md`
+file) and submit a PR.
