+# Phase 0: Bootstrap
+
+This module provisions the STACKIT PostgreSQL Flex instance, the `terraform_state` database, and the dedicated `tf_state_user`. Its state is kept locally (or in an independent CI/CD backend) to prevent dependency conflicts.
+
+## Implementation Steps
+
+1. Initialize Terraform with the default local backend:
+
+   ```sh
+   terraform init
+   ```
+
+2. Provision the PostgreSQL Flex resources:
+
+   ```sh
+   terraform apply
+   ```
+
+3. Extract the generated PostgreSQL connection string from the Terraform outputs. This URI is required to configure the remote backend in the next phase.
+
+   ```sh
+   terraform output -raw pg_connection_uri
+   ```

+# Phase 1: Example Infrastructure
+
+This module contains the core infrastructure configuration. It uses the `pg` backend to store state and enforce state locks via the STACKIT PostgreSQL Flex database provisioned in Phase 0.
+
+## Implementation Steps
+
+1. Create a `backend.conf` file in this directory and define the connection string using the credentials generated by the bootstrap module:
+
+   ```ini
+   conn_str = "postgres://tf_state_user:<PASSWORD>@<STACKIT_INSTANCE_HOST>:5432/terraform_state?sslmode=require"
+   ```
+
+2. Initialize Terraform and bind it to the remote PostgreSQL backend
+
+   ```sh
+   terraform init -backend-config=backend.conf
+   ```

+# STACKIT Terraform PostgreSQL Backend with State Locking
+
+This repository demonstrates how to configure STACKIT PostgreSQL Flex as a Terraform backend to enable remote state storage and native state locking.
+
+To resolve the circular dependency of provisioning a state backend using Terraform, the deployment is split into two isolated stages:
+
+1. **`00-bootstrap/`**: Provisions the backend infrastructure (PostgreSQL Flex instance, database and service user).
+2. **`01-example/`**: Represents the primary infrastructure, utilizing the provisioned PostgreSQL database as its remote backend.
