+# How to Verify Your Deployment is Working
+
+## 🔍 Current Status
+
+✅ **Code Changes**: All pushed to GitHub
+✅ **Workflow File**: Configured correctly
+⏳ **VERCEL_TOKEN**: **NEEDS TO BE ADDED** (see below)
+⏳ **GitHub Actions**: Waiting for token to run
+
+## 🎯 Next Steps to Complete Setup
+
+### Step 1: Add Vercel Token (REQUIRED)
+
+**⚠️ Without this, deployments won't work!**
+
+1. **Get Vercel Token**:
+   - Go to: https://vercel.com/account/tokens
+   - Click **"Create Token"**
+   - Name: `GitHub Actions Deployment`
+   - **Copy the token** (you won't see it again!)
+
+2. **Add to GitHub**:
+   - Go to: https://github.com/stellar-nexus-experience/demo-suite/settings/secrets/actions/new
+   - Name: `VERCEL_TOKEN`
+   - Value: Paste your token
+   - Click **"Add secret"**
+
+### Step 2: Check GitHub Actions Status
+
+Once the token is added:
+
+1. **View Actions**:
+   - Go to: https://github.com/stellar-nexus-experience/demo-suite/actions
+   - You should see the latest commit running
+   - Click on it to see detailed logs
+
+2. **Expected Jobs**:
+   - ✅ quality-check
+   - ✅ build  
+   - ✅ deploy-vercel (will work after you add token)
+
+### Step 3: Verify Deployment in Vercel
+
+1. **Check Vercel Dashboard**:
+   - Go to: https://vercel.com/dashboard
+   - Open your project
+   - Look for new deployment
+
+2. **Check Production Site**:
+   - Visit: https://stellar-nexus-experience.vercel.app
+   - Verify latest changes are live
+
+### Step 4: Verify Security Headers
+
+```bash
+# Check headers are deployed
+curl -I https://stellar-nexus-experience.vercel.app
+```
+
+Should see:
+- `strict-transport-security`
+- `content-security-policy`
+- `x-frame-options`
+- `x-content-type-options`
+- etc.
+
+### Step 5: Verify Google Verification File
+
+```bash
+curl https://stellar-nexus-experience.vercel.app/google27bfd857378807f2.html
+```
+
+Should return:
+```
+google-site-verification: google27bfd857378807f2.html
+```
+
+## 🧪 Quick Test
+
+Make a small change to test the full flow:
+
+```bash
+# Edit any file
+nano README.md  # or any file
+
+# Commit and push
+git add .
+git commit -m "test: verify deployment pipeline"
+git push
+```
+
+Then watch:
+1. GitHub Actions run
+2. Vercel deploy
+3. Website update
+
+## 🐛 Troubleshooting
+
+### GitHub Actions Shows "Secret not found"
+- **Cause**: VERCEL_TOKEN not added
+- **Fix**: Follow Step 1 above
+
+### Deployment Job Fails
+- **Cause**: Invalid or expired token
+- **Fix**: Regenerate token in Vercel
+
+### Build Succeeds but Deploy Fails
+- **Cause**: Vercel project not found
+- **Fix**: Check project name matches in Vercel dashboard
+
+### Website Not Updating
+- **Cause**: Vercel cache or deployment pending
+- **Fix**: Wait 2-3 minutes, check Vercel dashboard for deployment status
+
+## ✅ Success Checklist
