+## Files
+
+- `secret-git-credentials.yaml` - Git credentials for private repositories
+- `configmap-config.yaml` - Application configuration
+- `pvc.yaml` - Persistent volume claims for cache and metadata
+- `deployment.yaml` - Main application deployment
+- `service.yaml` - Service and optional ingress configuration
+
+## Quick Start
+
+### 1. Configure Git Credentials
+
+Edit `secret-git-credentials.yaml` and replace the placeholder tokens with your actual tokens:
+
+```yaml
+{
+  "credentials": [
+    {
+      "pattern": "github.com/mycompany/*",
+      "host": "github.com",
+      "username": "oauth2",
+      "token": "ghp_YOUR_ACTUAL_TOKEN_HERE"
+    }
+  ]
+}
+```
+
+**Pattern Matching Examples:**
+- `github.com/myorg/*` - Matches all repos under myorg
+- `github.com/myorg/specific-repo` - Matches only specific-repo
+- `gitlab.com/backend-team/*` - Matches all GitLab repos under backend-team
+- `*` - Fallback pattern (matches everything)
+
+**Credential Priority:**
+1. Most specific pattern wins (longest match)
+2. Fallback credential (`"fallback": true`)
+3. System git config (if no matches)
+
+### 2. Customize Configuration
+
+Edit `configmap-config.yaml` to adjust:
+- Cache size (`max_size_bytes`)
+- Security scanning settings
+- Upstream registries
+- Logging level
+
+### 3. Deploy to Kubernetes
+
+```bash
+# Create namespace (optional)
+kubectl create namespace gohoarder
+
+# Apply manifests
+kubectl apply -f pvc.yaml
+kubectl apply -f secret-git-credentials.yaml
+kubectl apply -f configmap-config.yaml
+kubectl apply -f deployment.yaml
+kubectl apply -f service.yaml
+
+# Verify deployment
+kubectl get pods -l app=gohoarder
+kubectl logs -l app=gohoarder -f
+```
+
+### 4. Configure Go Client
+
+```bash
+# Set GOPROXY environment variable
+export GOPROXY=http://gohoarder.default.svc.cluster.local:8080/go,direct
+
+# Or in your Dockerfile
+ENV GOPROXY=http://gohoarder.default.svc.cluster.local:8080/go,direct
+
+# Test with a private module
+go get github.com/mycompany/private-module@latest
+```
+
+## Advanced Configuration
+
+### Using External Secrets Operator (ESO)
+
+If you're using External Secrets Operator, uncomment the ExternalSecret section in `secret-git-credentials.yaml` and configure your SecretStore:
+
+```yaml
+apiVersion: external-secrets.io/v1beta1
+kind: ExternalSecret
+metadata:
+  name: gohoarder-git-credentials
+spec:
+  refreshInterval: 1h
+  secretStoreRef:
+    name: vault-backend
+    kind: SecretStore
+  target:
+    name: gohoarder-git-credentials
+  data:
+  - secretKey: credentials.json
+    remoteRef:
+      key: secret/gohoarder/git-credentials
+```
+
+### Storage Classes
+
+For production deployments, specify appropriate storage classes:
+
+```yaml
+# In pvc.yaml
+storageClassName: fast-ssd  # For cache (needs fast I/O)
+storageClassName: standard  # For metadata (smaller, less critical)
+```
+
+### Horizontal Pod Autoscaling
+
+```bash
+kubectl autoscale deployment gohoarder \
+  --cpu-percent=70 \
+  --min=2 \
+  --max=10
+```
+
+### Monitoring
+
+Check health and metrics:
+
+```bash
+# Health check
+kubectl port-forward svc/gohoarder 8080:8080
+curl http://localhost:8080/health
+
+# Metrics (Prometheus format)
+curl http://localhost:8080/metrics
+```
+
+## Multi-Organization Setup
+
+### Example 1: Multiple GitHub Organizations
+
+```json
+{
+  "credentials": [
+    {
+      "pattern": "github.com/company-frontend/*",
+      "host": "github.com",
+      "username": "oauth2",
+      "token": "ghp_frontend_team_token"
+    },
+    {
+      "pattern": "github.com/company-backend/*",
+      "host": "github.com",
+      "username": "oauth2",
+      "token": "ghp_backend_team_token"
+    },
+    {
+      "pattern": "github.com/company-infra/*",
+      "host": "github.com",
+      "username": "oauth2",
+      "token": "ghp_infra_team_token"
+    },
+    {
+      "pattern": "*",
+      "host": "*",
+      "username": "oauth2",
+      "token": "ghp_readonly_default_token",
+      "fallback": true
+    }
+  ]
+}
+```
+
+### Example 2: GitHub + GitLab
+
+```json
+{
+  "credentials": [
+    {
+      "pattern": "github.com/myorg/*",
+      "host": "github.com",
+      "username": "oauth2",
+      "token": "ghp_github_token"
+    },
+    {
+      "pattern": "gitlab.com/myteam/*",
+      "host": "gitlab.com",
+      "username": "oauth2",
+      "token": "glpat_gitlab_token"
+    }
+  ]
+}
+```
+
+### Example 3: Enterprise GitHub
+
+```json
+{
+  "credentials": [
+    {
+      "pattern": "github.enterprise.com/engineering/*",
+      "host": "github.enterprise.com",
+      "username": "oauth2",
+      "token": "ghp_enterprise_token"
+    }
+  ]
+}
+```
+
+## Security Best Practices
+
+1. **Token Scoping**: Use fine-grained personal access tokens with minimal permissions
+   - GitHub: Only `repo` scope needed for private repos
+   - GitLab: Only `read_repository` scope needed
+
+2. **Secret Rotation**: Regularly rotate tokens
+   ```bash
+   # Update secret
+   kubectl create secret generic gohoarder-git-credentials \
+     --from-file=credentials.json=./new-credentials.json \
+     --dry-run=client -o yaml | kubectl apply -f -
+
+   # Restart pods to pick up new credentials
+   kubectl rollout restart deployment gohoarder
+   ```
+
+3. **RBAC**: Limit who can read the secret
+   ```bash
+   kubectl create role secret-reader \
+     --verb=get,list \
+     --resource=secrets \
+     --resource-name=gohoarder-git-credentials
+   ```
+
+4. **Audit Logging**: Enable Kubernetes audit logging for secret access
+
+5. **Network Policies**: Restrict which pods can access GoHoarder
+   ```yaml
+   apiVersion: networking.k8s.io/v1
+   kind: NetworkPolicy
+   metadata:
+     name: allow-from-build-namespace
+   spec:
+     podSelector:
+       matchLabels:
+         app: gohoarder
+     ingress:
+     - from:
+       - namespaceSelector:
+           matchLabels:
+             name: build-namespace
+   ```
+
+## Troubleshooting
+
+### Check if credentials are loaded
+
+```bash
+# Check logs for credential loading
+kubectl logs -l app=gohoarder | grep "Loaded git credentials"
+
+# Expected output:
+# {"level":"info","file":"/etc/gohoarder/git-credentials.json","credentials":3,"message":"Loaded git credentials from file"}
+# {"level":"debug","pattern":"github.com/myorg/*","host":"github.com","message":"Registered credential pattern"}
+```
+
+### Test credential pattern matching
+
+```bash
+# Enable debug logging
+kubectl set env deployment/gohoarder LOG_LEVEL=debug
+
+# Watch logs during a go get request
+kubectl logs -l app=gohoarder -f
+```
+
+### Common Issues
+
+**Issue**: `git clone failed: authentication required`
+- **Cause**: No matching credential pattern
+- **Solution**: Check pattern syntax in credentials.json, ensure it matches the module path
+
+**Issue**: `Failed to load git credentials`
+- **Cause**: Secret not mounted or JSON syntax error
+- **Solution**: Verify secret exists and JSON is valid
+  ```bash
+  kubectl get secret gohoarder-git-credentials
+  kubectl get secret gohoarder-git-credentials -o jsonpath='{.data.credentials\.json}' | base64 -d | jq .
+  ```
+
+**Issue**: Module fetch slow
+- **Cause**: Git clone timeout or large repository
+- **Solution**: Increase timeout in config.yaml or use upstream proxy for public modules
+
+## Performance Tuning
+
+### Cache Configuration
+
+```yaml
+cache:
+  max_size_bytes: 107374182400  # 100GB for large organizations
+  default_ttl: 168h              # 7 days for stable modules
+```
+
+### Resource Limits
+
+For high-traffic deployments:
+
+```yaml
+resources:
+  requests:
+    memory: "2Gi"
+    cpu: "1000m"
+  limits:
+    memory: "8Gi"
+    cpu: "4000m"
+```
+
+### Replicas
+
+Run multiple replicas for high availability:
+
+```yaml
+spec:
+  replicas: 3
+```
+
+## Backup and Recovery
+
+### Backup Metadata Database
+
+```bash
+# Backup SQLite database
+kubectl exec -it deployment/gohoarder -- \
+  sqlite3 /var/lib/gohoarder/gohoarder.db ".backup /tmp/backup.db"
+
+kubectl cp gohoarder-pod:/tmp/backup.db ./gohoarder-backup-$(date +%Y%m%d).db
+```
+
+### Restore from Backup
+
+```bash
+kubectl cp ./gohoarder-backup-20260102.db gohoarder-pod:/var/lib/gohoarder/gohoarder.db
+kubectl rollout restart deployment gohoarder
+```
+
+## Integration Examples
+
+### CI/CD Pipeline (GitHub Actions)
+
+```yaml
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v3
+
+    - name: Set up Go
+      uses: actions/setup-go@v4
+      with:
+        go-version: '1.21'
+
+    - name: Configure GOPROXY
+      run: |
+        echo "GOPROXY=http://gohoarder.company.internal:8080/go,direct" >> $GITHUB_ENV
+
+    - name: Build
+      run: go build ./...
+```
+
+### Dockerfile
+
+```dockerfile
+FROM golang:1.21-alpine
