+# Lucee UI for Rabbit CRUD
+
+UI publishes CRUD actions to RabbitMQ and reads results from Postgres.
+
+## Behavior
+
+- Insert/Update/Delete actions are queued via RabbitMQ.
+- A status banner shows when the action was queued and when it appears in Postgres.
+- The UI reads the latest rows from the table defined by `PG_TABLE`.
+
+## Environment variables
+
+Lucee datasource (required):
+- `testds_connectionString`
+- `testds_username`
+- `testds_password`
+- `testds_class` (org.postgresql.Driver)
+- `testds_bundleName` (org.postgresql.jdbc)
+- `testds_bundleVersion` (42.6.0)
+- `testds_connectionLimit` (5)
+- `testds_liveTimeout` (15)
+- `testds_validate` (false)
+
+RabbitMQ (required):
+- `RABBIT_HOST`
+- `RABBIT_PORT` (default 5672)
+- `RABBIT_USER`
+- `RABBIT_PASSWORD`
+- `RABBIT_VHOST` (default `/`)
+- `RABBIT_QUEUES` (default `crud_queue`)
+- `RABBIT_DURABLE` (default `true`)
+
+Optional:
+- `PG_TABLE` (default `rabbit_messages`)
+
+## Notes
+
+This app uses RabbitMQ Java client JARs located in `lib/`.
