-Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+Specify each parameter using the `--set key=value[,key=value]` argument:
 
 ```console
-$ helm install my-release podinfo/podinfo \
+$ helm upgrade -i podinfo oci://ghcr.io/stefanprodan/charts/podinfo \
   --set=serviceMonitor.enabled=true,serviceMonitor.interval=5s
 ```
 
 To add custom annotations you need to escape the annotation key string:
 
 ```console
-$ helm upgrade -i my-release podinfo/podinfo \
+$ helm upgrade -i podinfo oci://ghcr.io/stefanprodan/charts/podinfo \
---set podAnnotations."appmesh\.k8s\.aws\/preview"=enabled
+--set podAnnotations."toolkit\.fluxcd\.io\/tenant"=dev-team
 ```
 
-Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

+# Database Setup
+
+This directory contains the Kubernetes manifests to simulate a database setup
+with a primary database, read replicas, and scheduled maintenance tasks using CronJobs.
+
+## Components
+
+### Core Resources
+
+| Resource | File | Description |
+|----------|------|-------------|
+| ServiceAccount | `serviceaccount.yaml` | Shared service account for all database workloads |
+| PVC | `pvc-primary.yaml` | 1Gi persistent storage for primary database |
+| StatefulSet | `statefulset-primary.yaml` | Primary database with persistent storage at `/data` |
+| Deployment | `deployment-replica.yaml` | Read replica deployment |
+| Service (Headless) | `service-primary.yaml` | Headless service for StatefulSet |
+| Service | `service-replica.yaml` | ClusterIP service for replicas |
+| HPA | `hpa-replica.yaml` | Autoscaler for replicas (2-3 pods, 99% CPU) |
+
+### CronJobs
+
+| CronJob | Schedule | Duration | TTL Cleanup | Description |
+|---------|----------|----------|-------------|-------------|
+| `rollup-daily` | Every 10 min | ~1 min | 1 hour | Daily rollup simulation (6 iterations) |
+| `rollup-weekly` | Every 30 min | ~2 min | 1 day | Weekly rollup simulation (12 iterations) |
+| `backup-daily` | Daily at midnight | ~1 min | 1 day | Backup simulation (configured to fail) |
+
+### Scripts
+
+Located in `scripts/` directory:
+
+- `rollup.sh` - Rollup simulation script with configurable steps via `ROLLUP_STEPS` env var
+- `backup.sh` - Backup simulation script with configurable exit code via `BACKUP_EXIT` env var
+
+## Labels
+
+All resources use Kubernetes recommended labels:
+
+- `app.kubernetes.io/name` - Component name
+- `app.kubernetes.io/part-of: database` - Part of database application
+
+## Configuration
+
+### Primary Database
+- **Port**: 3306 (MySQL standard)
+- **Storage**: 1Gi PersistentVolumeClaim mounted at `/data`
+- **Service**: Headless (`clusterIP: None`) for StatefulSet
+
+### Replica Database
+- **Port**: 3306
+- **Scaling**: HPA with 2-3 replicas at 99% CPU utilization
+- **Service**: ClusterIP
+
+### CronJob Scripts
+
+The scripts check database-replica health before running:
+
+```sh
+podcli check http database-replica:3306/readyz
+```
+
+## Usage
+
+Deploy with Kustomize:
+
+```bash
+kubectl apply -k deploy/bases/database
+```
+
+Or include in an overlay:
+
+```yaml
+# kustomization.yaml
+resources:
+  - ../../bases/database
+```
