+# Fix Placeholders - Quick Reference Guide
+
+## 🔴 Critical - Must Fix Before Production
+
+### 1. Replace Organization Namespace
+
+**Find and Replace**:
+- `proxmox.yourorg.io` → `proxmox.YOURACTUALORG.io`
+- `github.com/yourorg` → `github.com/YOURACTUALORG`
+- `yourorg` → `YOURACTUALORG`
+
+**Files**:
+```bash
+# Use find and replace in your editor
+grep -r "yourorg" crossplane-provider-proxmox/
+grep -r "yourorg" gitops/
+grep -r "yourorg" portal/
+```
+
+### 2. Replace Domain Placeholders
+
+**Find and Replace**:
+- ✅ Updated to use `sankofa.nexus` as the project domain
+- Replace with your actual domain in production if different
+- `example.com` → `YOURACTUALDOMAIN.com` (in production configs)
+- `sankofa.nexus` → `YOURACTUALDOMAIN.com` (if different)
+
+**Files**:
+```bash
+grep -r "yourdomain\|example.com" docs/
+grep -r "sankofa.nexus" api/src/
+```
+
+### 3. Update GitOps Repository URL
+
+**File**: `gitops/apps/argocd/application.yaml`
+```yaml
+source:
+  repoURL: https://github.com/YOURACTUALORG/sankofa-phoenix
+```
+
+### 4. Implement Credential Handling
+
+**File**: `crossplane-provider-proxmox/pkg/controller/virtualmachine/controller.go`
+
+Replace placeholder credentials (line ~169) with:
+```go
+func (r *ProxmoxVMReconciler) getCredentials(ctx context.Context, config *proxmoxv1alpha1.ProviderConfig) (*credentials, error) {
+    if config.Spec.Credentials.SecretRef == nil {
+        return nil, fmt.Errorf("no secret reference in provider config")
+    }
+
+    secretRef := config.Spec.Credentials.SecretRef
+    
+    // Get secret from Kubernetes
+    secret := &corev1.Secret{}
+    secretKey := client.ObjectKey{
+        Namespace: secretRef.Namespace,
+        Name:      secretRef.Name,
+    }
+    
+    if err := r.Get(ctx, secretKey, secret); err != nil {
+        return nil, errors.Wrap(err, "cannot get secret")
+    }
+    
+    // Parse credentials from secret
+    username := string(secret.Data["username"])
+    password := string(secret.Data["password"])
+    
+    if username == "" || password == "" {
+        return nil, fmt.Errorf("username or password missing in secret")
+    }
+    
+    return &credentials{
+        Username: username,
+        Password: password,
+    }, nil
+}
+```
+
+**File**: `crossplane-provider-proxmox/pkg/controller/resourcediscovery/controller.go`
+
+Replace empty credentials (lines ~135, ~164) with proper secret retrieval.

+
+## 🟡 Medium Priority
+
+### 5. Replace Console.log with Proper Logging
+
+**Install logging library**:
+```bash
+cd api
+pnpm add winston
+pnpm add -D @types/winston
+```
+
+**Create logger** (`api/src/lib/logger.ts`):
+```typescript
+import winston from 'winston'
+
+export const logger = winston.createLogger({
+  level: process.env.LOG_LEVEL || 'info',
+  format: winston.format.combine(
+    winston.format.timestamp(),
+    winston.format.json()
+  ),
+  transports: [
+    new winston.transports.Console({
+      format: winston.format.simple()
+    })
+  ]
+})
+```
+
+**Replace console.log**:
+```typescript
+// Before
+console.log('Message')
+console.error('Error', error)
+
+// After
+import { logger } from '../lib/logger'
+logger.info('Message')
+logger.error('Error', { error })
+```
+
+### 6. Generate Blockchain Contract Types
+
+**Install typechain**:
+```bash
+cd blockchain
+pnpm add -D @typechain/ethers-v6 typechain
+```
+
+**Generate types**:
+```bash
+pnpm exec typechain --target ethers-v6 --out-dir ../api/src/types/contracts artifacts/contracts/**/*.json
+```
+
+**Update blockchain service** to use generated types.
+
+---
+
+## 🟢 Low Priority
+
+### 7. Create Helm Charts
+
+Create `helm/sankofa-phoenix/` with:
+- `Chart.yaml`
+- `values.yaml`
+- `templates/` directory
+
+### 8. Add API Documentation
+
+**Install GraphQL tools**:
+```bash
+cd api
+pnpm add -D @graphql-codegen/cli @graphql-codegen/typescript
+```
+
+**Generate types and docs**:
+```bash
+pnpm exec graphql-codegen
+```
