+## Schema
+
+### Required
+
+- `project_id` (String) STACKIT project ID.
+
+### Read-Only
+
+- `area_id` (String) The area ID to which the project belongs to.
+- `created_at` (String) Date-time when the project was created.
+- `id` (String) Terraform's internal resource ID. It is structured as "`project_id`".
