+# Development
+
+## Local Testing
+
+`make test_in_containers` will run all integration tests against all supported
+minor versions of Python. It does not currently run any style or lint tests,
+and the coverage report it generates points to an absolute path on the
+container (`/src/`) and is therefore not terribly useful, but it does run all
+of the integration tests (the other tests and output are planned to be added).
+
+`make test` will work to run tests against whatever version of Python is
+`python3` on your host. It also runs style and lint checks, and generates a
+coverage report from the integration tests.
