+# PGSQL schema generator
+During the `generate-resources` phase of the Maven build pgsql-schema-generator will run (see `exec-maven-plugin` in the
+`teiv` POM), v1 of the SQL files in this directory are **automatically overwritten** if there are changes to the YANG
+models.
+
+**NOTE**: After regenerating SQL files, ensure the new v1 SQL files are checked in to version control. This ensures
+that the generated SQL files remain in sync with the resource SQL files.
