 # Test script for 'synapse_port_db'.
-#   - sets up synapse and deps
+#   - configures synapse and a postgres server.
 #   - runs the port script on a prepopulated test sqlite db
 #   - also runs it against an new sqlite db
-
+#
+# Expects Synapse to have been already installed with `poetry install --extras postgres`.
+# Expects `poetry` to be available on the `PATH`.
