+## Deployment Procedures
+
+### Build and Deploy Preview (from `main`)
+```bash
+# 1. Switch to main branch
+git checkout main
+
+# 2. Build image via Cloud Build
+gcloud builds submit --tag asia-northeast1-docker.pkg.dev/xzerolab-480008/cloud-run-source-deploy/accounts.svc.plus/preview-accounts-svc-plus:latest --project xzerolab-480008
+
+# 3. Apply Cloud Run configuration
+gcloud run services replace deploy/gcp/cloud-run/preview-service.yaml --project xzerolab-480008 --region asia-northeast1
+
+# 4. Ensure public access
+gcloud run services add-iam-policy-binding preview-accounts-svc-plus --project xzerolab-480008 --region asia-northeast1 --member="allUsers" --role="roles/run.invoker"
+```
+
+### Build and Deploy Production (from `release/v0.1`)
+```bash
+# 1. Switch to release branch
+git checkout release/v0.1
+
+# 2. Build image via Cloud Build
+gcloud builds submit --tag asia-northeast1-docker.pkg.dev/xzerolab-480008/cloud-run-source-deploy/accounts.svc.plus/accounts-svc-plus:v0.1 --project xzerolab-480008
+
+# 3. Apply Cloud Run configuration
+# Note: Ensure the image path in service.yaml matches the versioned tag
+gcloud run services replace deploy/gcp/cloud-run/prod-service.yaml --project xzerolab-480008 --region asia-northeast1
+```
+
+## Infrastructure Components

+- **Secrets**:
+  - `postgres-password`: Database access.
+  - `internal-service-token`: RPC/Internal communication.
+  - `stunnel-config`: Sidecar tunnel settings.
