+### INIT_CONFIG
+
+The `INIT_CONFIG` environment variable allows you to configure the initial setup of your self-hosted Layer5 Cloud provider. This variable accepts a JSON string that defines the provider initialization configuration.
+
+#### Purpose
+
+`INIT_CONFIG` enables you to:
+- Pre-configure provider settings during deployment
+- Automate initial setup for consistent deployments  
+- Define custom provider configurations without manual intervention
+
+#### Usage
+
+Set the `INIT_CONFIG` environment variable with a JSON configuration string:
+
+```bash
+export INIT_CONFIG='{"provider": {"name": "my-provider", "settings": {...}}}'
+```
+
+For Docker deployments:
+
+```bash
+# example
+docker run -e INIT_CONFIG='{"provider": {"name": "my-provider"}}' layer5/meshery-cloud
+```
+
+For Kubernetes deployments, add to your deployment manifest:
+
+```yaml
+env:
+  - name: INIT_CONFIG
+    value: '{"provider": {"name": "my-provider", "settings": {...}}}'
+```
+
+{{< alert type="info" title="Note" >}}
+The INIT_CONFIG variable is only processed during the initial startup. Subsequent restarts will not reprocess this configuration.
+{{< /alert >}}
+
+#### Configuration Schema
+
+The `INIT_CONFIG` JSON structure supports the following fields:
+
+- `provider.name`: The name of your provider instance
+- `provider.settings`: Custom provider settings specific to your deployment

+
+## Provider Configuration Planning
+
+When planning your self-hosted Layer5 Cloud deployment, consider how you will initialize and configure your provider instance. The `INIT_CONFIG` environment variable enables you to automate provider configuration during deployment.
+
+### Configuration Strategy
+
+Before deploying, plan your configuration approach:
+
+1. **Provider Identity**: Define your provider name and identification
+2. **Initial Settings**: Determine which settings need to be configured at startup
+3. **Configuration Management**: Decide how configuration will be managed (environment variables, secrets, config files)
+4. **Update Strategy**: Plan for configuration updates and changes over time
+
+### Provider Admin Organization Initialization
+
+The Provider Admin organization is a special organization identified by the hardcoded UUID `11111111-1111-1111-1111-111111111111`. It represents the root administrative organization for the cloud platform.
+
+#### Configuration Format
+
+The `INIT_CONFIG` environment variable accepts a YAML configuration with the following structure:
+
+```yaml
+organization:
+  name: "Layer5"
+  description: "The uber organization for all things Layer5."
+  country: "United States"
+  region: "North America"
+
+user:
+  first_name: "Admin"
+  last_name: "User"
+  email: "[email protected]"
+  username: "[email protected]"  # Optional, defaults to email if not provided
+  password: "change-me-on-first-login"  # Required
+```
+
+#### Setting the Environment Variable
+
+To enable Provider Admin organization initialization, set the `INIT_CONFIG` environment variable with the entire YAML configuration as its value:
+
+```bash
+INIT_CONFIG='organization:
+  name: "Layer5"
+  description: "The uber organization for all things Layer5."
+  country: "United States"
+  region: "North America"
+
+user:
+  first_name: "Admin"
+  last_name: "User"
+  email: "[email protected]"
+  username: "[email protected]"
+  password: "change-me-on-first-login"'
+```
+
+#### Required and Optional Fields
+
+**Organization:**
+- `name`: Name of the provider organization (required)
+- `description`: Description of the organization (optional)
+- `country`: Country where the organization is located (optional)
+- `region`: Region where the organization is located (optional)
+
+**User:**
+- `first_name`: First name of the provider admin user (required)
+- `last_name`: Last name of the provider admin user (required)
+- `email`: Email address of the provider admin user (required)
+- `username`: Username for the provider admin user (optional, defaults to email)
+- `password`: Password for the provider admin user (required)
+
+#### Initialization Process
+
+When the server starts and `INIT_CONFIG` is set:
+
+1. The YAML configuration is parsed and validated
+2. The system checks if the provider organization already exists (by UUID `11111111-1111-1111-1111-111111111111`)
+3. If the organization exists, initialization is skipped
+4. If the organization does not exist:
+   - Kratos identity is created with password credentials for authentication
+   - Provider admin user is created
+   - Admin and MeshMap roles are assigned to the user
+   - Provider organization is created with the hardcoded UUID
+   - User is added to the provider organization with organization admin role
+
+#### Idempotency
+
+The initialization process is idempotent:
+- Running the server multiple times with the same configuration will not create duplicate organizations
+- If the provider organization already exists, the initialization is skipped
+- No errors are thrown if the organization already exists
+
+#### Error Handling
+
+If initialization fails:
+- Errors are logged using MeshKit logger
+- The server continues to start (non-fatal error)
+- All database operations are wrapped in a transaction for atomicity
+- If any step fails, all changes are rolled back
+
+### Deployment Options
+
+You can set the `INIT_CONFIG` environment variable using several methods:
+
+**Option A (Helm with inline values)**: Include `initConfig` in the Helm `values.yaml` file with the YAML configuration as a multiline string
+
+**Option B (Helm with --set-file flag)**: Use `--set-file` to load configuration from a separate file:
+```bash
+helm install meshery-cloud ./install/kubernetes/helm/layer5-cloud \
+  --set-file env.initConfig=./config/provider-init.yaml.example
+```
+
+**Option C (Direct environment variable)**: Set the `INIT_CONFIG` environment variable with the YAML content as a string
+
+### Using INIT_CONFIG for Automated Setup
+
+The `INIT_CONFIG` environment variable allows you to pre-configure your provider during deployment, eliminating manual setup steps. This is particularly valuable for:
+
+- **Reproducible Deployments**: Ensure consistent configuration across environments
+- **CI/CD Integration**: Automate deployments with predefined configurations
+- **Infrastructure as Code**: Manage provider configuration alongside your infrastructure
+
+For detailed configuration options, see the configuration schema below.
+
+{{< alert type="warning" title="Important" >}}
+Plan your INIT_CONFIG carefully as it is only processed during initial startup. Changes require redeployment or manual configuration updates.
