+### Testing
+
+To run the test suite against all supported versions of PostgreSQL and
+Node.js locally, you will need to install and run Docker, and then run
+
+    ./test_all_versions.sh
+
+This will take a while, and consume a lot of bandwidth downloading Docker
+images.
+
+Due to a [bug in npm][npmbug], the output is very verbose, but with a bit of
+scrolling, you should hopefully see green checkmarks for every test run.
