 # Infrastructure as Code
 
-Home for my infra-as-code - terraform configs.
+This directory contains Infrastructure as Code (IaC) configurations using Terraform, primarily for
+managing storage and backend services.
 
-Kubernetes's yaml are stored in a separate repo:
-[ryan4yin/k8s-gitops](https://github.com/ryan4yin/k8s-gitops).

+## Services Overview
+
+### MinIO Storage
+
+- **Loki Buckets**: Dedicated storage for Grafana Loki log aggregation
+- **Terraform Backend**: Centralized state management for all Terraform configurations
+
+### External Resources
+
+- **Kubernetes YAML**: Managed in separate repository
+  [ryan4yin/k8s-gitops](https://github.com/ryan4yin/k8s-gitops)
+- **Secrets Management**: Handled via agenix in [../secrets](../secrets/)
+
+## Usage
+
+Each subdirectory contains its own Terraform configuration:
+
+1. **Navigate to specific service**:
+
+   ```bash
+   cd infra/minio/loki
+   ```
+
+2. **Deploy configuration**:
+
+   ```bash
+   ./run.sh
+   ```
+
+3. **Manual deployment**:
+   ```bash
+   terraform init
+   terraform plan
+   terraform apply
+   ```
+
+## Security Considerations
+
+- All storage buckets are configured with appropriate access policies
+- State files are encrypted at rest
+- Access credentials are managed through environment variables
+- Network access is restricted to necessary hosts only
