+# MariaDB CRUD test stand
+
+This Terraform root manages one MariaDB cluster, the `maria` database, three CRUD apps, and an HTTP readiness check.
+
+The Lucee, Flask, and Node.js apps share the `crud_items` table. Their source repositories are the corresponding repositories under `terraform/` on Gitea. The HTTP service uses the image `naeel/mariadb-check:0.1`; build and publish that image before applying this configuration.
+
+## Configuration
+
+`terraform.tfvars` contains the Nubes API token and the resource realm. It is ignored by Git. The example file contains no credentials.
+
+## Commands
+
+```sh
+terraform init
+terraform validate
+terraform plan
+```
+
+Review the plan before applying it. The database is a managed resource and may be deleted by Terraform destroy.
