+# Key Management Quick Start
+
+This guide gets you started with the automated key management system in minutes.
+
+## 📋 Prerequisites
+
+- GitHub repository with Actions enabled
+- Repository admin access (for secrets management)
+- Bun or Node.js installed (for local usage)
+
+## 🚀 Quick Start
+
+### 1. Add KEYFINDER_SECRET (Optional)
+
+If you want to fetch keys from external sources:
+
+1. Go to your repository → Settings → Secrets and variables → Actions
+2. Click "New repository secret"
+3. Name: `KEYFINDER_SECRET`
+4. Value: Your external key finder authentication token
+5. Click "Add secret"
+
+### 2. Configure Required Keys
+
+Edit `key-manager.config.json` to define your application's keys:
+
+```json
+{
+  "requiredKeys": [
+    {
+      "name": "YOUR_API_KEY",
+      "description": "Description of what this key is for",
+      "required": true,
+      "inject": [".env"]
+    }
+  ]
+}
+```
+
+### 3. Run Key Management
+
+#### Option A: Manual Trigger (Recommended for first run)
+
+1. Go to Actions tab → Key Management
+2. Click "Run workflow"
+3. Select `check` command to see what keys exist
+4. Click "Run workflow"
+
+#### Option B: Integrate with CI/CD
+
+Add to your workflow file:
+
+```yaml
+jobs:
+  your-build:
+    # ... your build steps ...
+
+  manage-keys:
+    needs: your-build
+    uses: ./.github/workflows/key-manager.yml
+    secrets: inherit
+    with:
+      command: 'scan'
+```
+
+#### Option C: Command Line
+
+```bash
+cd scripts
+export GITHUB_TOKEN="your_token"
+export GITHUB_REPOSITORY="owner/repo"
+bunx tsx key-manager.ts check
+```
+
+## 📊 Understanding the Output
+
+When you run the key manager, you'll see:
+
+```
+🔐 Automated Key Management System
+══════════════════════════════════════════════════
+
+🔧 Initializing Key Manager...
+✅ Loaded configuration with 13 key definitions
+
+📊 Scanning for required keys...
+  • DATABASE_URL - PostgreSQL database connection string
+  • ENCRYPTION_KEY - Encryption key for environment variables
+  ...
+
+🔍 Checking GitHub repository secrets...
+  ✓ DATABASE_URL - found in GitHub secrets
+  ✗ SOME_API_KEY - not found in GitHub secrets
+✅ Found 8/13 keys in GitHub secrets
+
+📋 Key Management Summary
+══════════════════════════════════════════════════
+Total keys defined: 13
+  Required: 7
+  Optional: 6
+```
+
+## 🔑 Common Commands
+
+### Check existing keys
+```bash
+bunx tsx scripts/key-manager.ts check
+```
+
+### Scan and manage all keys
+```bash
+bunx tsx scripts/key-manager.ts scan
+```
+
+### Inject keys from environment
+```bash
+export DATABASE_URL="postgresql://..."
+bunx tsx scripts/key-manager.ts inject
+```
+
+## 🛡️ Security Features
+
+- ✅ **Automatic masking**: All key values are masked in logs
+- ✅ **Memory clearing**: Sensitive data is cleared after processing
+- ✅ **GitHub secrets**: Keys stored securely in repository secrets
+- ✅ **No plain text**: Keys never written to plain text files in commits
+
+## 🔄 Typical Workflow
+
+1. **Development**: Add new API integration to your app
+2. **Configuration**: Update `key-manager.config.json` with new key
+3. **Storage**: Add key value to GitHub secrets manually or via key manager
+4. **Deployment**: Key manager injects keys during build/deploy
+5. **Cleanup**: Key manager clears sensitive data from workflow memory
+
+## 📝 Adding a New Key
+
+1. Edit `key-manager.config.json`:
+
+```json
+{
+  "name": "STRIPE_API_KEY",
+  "description": "Stripe payment processing API key",
+  "pattern": "^sk_",
+  "required": false,
+  "inject": [".env"]
+}
+```
+
+2. Add the key to GitHub secrets:
+   - Go to Settings → Secrets → New repository secret
+   - Name: `STRIPE_API_KEY`
+   - Value: `sk_test_...`
+
+3. Run the key manager:
+```bash
+bunx tsx scripts/key-manager.ts check
+```
+
+## ⚠️ Troubleshooting
+
+### "GITHUB_TOKEN environment variable is required"
+
+**Local usage**: Export your GitHub token:
+```bash
+export GITHUB_TOKEN="ghp_..."
+export GITHUB_REPOSITORY="owner/repo"
+```
+
+**GitHub Actions**: Ensure workflow has permissions:
+```yaml
+permissions:
+  contents: read
+  secrets: write
+```
+
+### Keys not being injected
+
+1. Check `key-manager.config.json` has correct `inject` array
+2. Verify injection target path exists
+3. Check file permissions
+
+### External key fetch failing
+
+1. Verify `KEYFINDER_SECRET` is set in repository secrets
+2. Check external endpoint is accessible
+3. Verify authentication credentials
+
+## 🎯 Next Steps
+
+1. ✅ Run `check` command to audit existing keys
+2. ✅ Add missing keys to GitHub secrets
+3. ✅ Integrate with your CI/CD pipeline
+4. ✅ Set up weekly key audits
+5. ✅ Document key rotation schedule

+- [Usage Examples](KEY_MANAGEMENT_EXAMPLES.md)
+- [GitHub Issues](https://github.com/al7566/sim/issues)
+
+## 💡 Pro Tips
+
+- Start with `dry_run: true` to test changes safely
+- Use `check` command regularly to audit keys
+- Document key sources in the config file
+- Set calendar reminders for key rotation
+- Use environment-specific secrets (PROD_*, STAGING_*)
