+## Quick Start (Automated Setup)
+
+**✨ NEW: Automated setup scripts available!**
+
+### Option A: Fully Automated Setup (Recommended)
+
+```bash
+# Step 1: Verify Stripe API connection
+node scripts/test-stripe-connection.js
+
+# Step 2: Create products and prices automatically
+node scripts/setup-stripe-products.js
+
+# Step 3: Server will restart automatically - prices now configured!
+
+# Step 4: Test the complete integration
+node scripts/test-stripe-integration.js
+
+# Step 5: Set up webhooks for local testing (requires Stripe CLI)
+./scripts/stripe-webhook-setup.sh
+```
+
+**That's it!** All products, prices, and configuration are set up automatically.
+
+### What the Scripts Do
+
+1. **test-stripe-connection.js** - Verifies test API keys work and shows existing products/prices
+2. **setup-stripe-products.js** - Creates the Tractatus product and 3 monthly price tiers with multi-currency support
+3. **test-stripe-integration.js** - Tests checkout session creation for both monthly and one-time donations
+4. **stripe-webhook-setup.sh** - Guides you through Stripe CLI installation and webhook setup
+
+### Option B: Manual Setup
+
+Continue to Section 1 below for step-by-step manual instructions.

+## CRITICAL: HTML Caching Rules
+
+**MANDATORY REQUIREMENT**: HTML files MUST be delivered fresh to users without requiring cache refresh.
+
+### The Problem
+Service worker caching HTML files caused deployment failures where users saw OLD content even after deploying NEW code. Users should NEVER need to clear cache manually.
+
+### The Solution (Enforced as of 2025-10-17)
+
+**Service Worker** (`public/service-worker.js`):
+- HTML files: Network-ONLY strategy (never cache, always fetch fresh)
+- Exception: `/index.html` only for offline fallback
+- Bump `CACHE_VERSION` constant whenever service worker logic changes
+
+**Server** (`src/server.js`):
+- HTML files: `Cache-Control: no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0`
+- This ensures browsers never cache HTML pages
+- CSS/JS: Long cache OK (use version parameters for cache-busting)
+
+**Version Manifest** (`public/version.json`):
+- Update version number when deploying HTML changes
+- Service worker checks this for updates
+- Set `forceUpdate: true` for critical fixes
+
+### Deployment Rules for HTML Changes
+
+When deploying HTML file changes:
+
+1. **Verify service worker never caches HTML** (except index.html)
+   ```bash
+   grep -A 10 "HTML files:" public/service-worker.js
+   # Should show: Network-ONLY strategy, no caching
+   ```
+
+2. **Verify server sends no-cache headers**
+   ```bash
+   grep -A 3 "HTML files:" src/server.js
+   # Should show: no-store, no-cache, must-revalidate
+   ```
+
+3. **Bump version.json if critical content changed**
+   ```bash
+   # Edit public/version.json
+   # Increment version: 1.1.2 → 1.1.3
+   # Update changelog
+   # Set forceUpdate: true
+   ```
+
+4. **After deployment, verify headers in production**
+   ```bash
+   curl -s -I https://agenticgovernance.digital/koha.html | grep -i cache-control
+   # Expected: no-store, no-cache, must-revalidate
+
+   curl -s https://agenticgovernance.digital/koha.html | grep "<title>"
+   # Verify correct content showing
+   ```
+
+5. **Test in incognito window**
+   - Open https://agenticgovernance.digital in fresh incognito window
+   - Verify new content loads immediately
+   - No cache refresh should be needed
+
+### Testing Cache Behavior
+
+**Before deployment:**
+```bash
+# Local: Verify server sends correct headers
+curl -s -I http://localhost:9000/koha.html | grep cache-control
+# Expected: no-store, no-cache
+
+# Verify service worker doesn't cache HTML
+grep "endsWith('.html')" public/service-worker.js -A 10
+# Should NOT cache responses, only fetch
+```
+
+**After deployment:**
+```bash
+# Production: Verify headers
+curl -s -I https://agenticgovernance.digital/<file>.html | grep cache-control
+
+# Production: Verify fresh content
+curl -s https://agenticgovernance.digital/<file>.html | grep "<title>"
+```
+
+### Incident Prevention
+
+**Lesson Learned** (2025-10-17 Koha Deployment):
+- Deployed koha.html with reciprocal giving updates
+- Service worker cached old version
+- Users saw old content despite fresh deployment
+- Required THREE deployment attempts to fix
+- Root cause: Service worker was caching HTML with network-first strategy
+
+**Prevention**:
+- Service worker now enforces network-ONLY for all HTML (except offline index.html)
+- Server enforces no-cache headers
+- This checklist documents the requirement architecturally

 ## Deployment Best Practices

 ### DO:
@ -570,6 +670,8 @@ Keep a deployment log in: `docs/deployments/YYYY-MM.md`
 - ✅ Document all deployments
 - ✅ Keep rollback procedure tested and ready
 - ✅ Communicate with team before major deployments
+- ✅ **CRITICAL: Verify HTML cache headers before and after deployment**
+- ✅ **CRITICAL: Test in incognito window after HTML deployments**

 ### DON'T:
 - ❌ Deploy on Friday afternoon (limited time to fix issues)
@ -579,6 +681,8 @@ Keep a deployment log in: `docs/deployments/YYYY-MM.md`
 - ❌ Deploy when tired or rushed
 - ❌ Deploy without ability to rollback
 - ❌ Forget to restart services after backend changes
+- ❌ **CRITICAL: Never cache HTML files in service worker (except offline fallback)**
+- ❌ **CRITICAL: Never ask users to clear their browser cache - fix it server-side**
