+## Deployment to GitHub Pages (FREE)
+
+This project uses a two-repository setup to keep source code private while hosting the app for free.
+
+### One-Time Setup
+
+#### 1. Create Public Deployment Repo
+
+Go to https://github.com/new and create:
+- **Name**: `seedpgp-web-app` (or any name you prefer)
+- **Visibility**: **Public**
+- **Don't** initialize with README, .gitignore, or license
+
+#### 2. Configure Vite Base Path
+
+Edit `vite.config.ts`:
+
+```typescript
+export default defineConfig({
+  plugins: [react()],
+  base: '/seedpgp-web-app/', // Match your public repo name
+})
+```
+
+#### 3. Build and Deploy
+
+```bash
+# Build the production bundle
+bun run build
+
+# Initialize git in dist folder
+cd dist
+git init
+git add .
+git commit -m "Deploy seedpgp v1.1.0"
+
+# Push to your public repo
+git remote add origin https://github.com/kccleoc/seedpgp-web-app.git
+git branch -M main
+git push -u origin main
+
+# Return to project root
+cd ..
+```
+
+#### 4. Enable GitHub Pages
+
+1. Go to `https://github.com/kccleoc/seedpgp-web-app/settings/pages`
+2. **Source**: Deploy from a branch
+3. **Branch**: Select `main` → `/` (root)
+4. Click **Save**
+
+Wait 1-2 minutes, then visit: **https://kccleoc.github.io/seedpgp-web-app/**
+
+---
+
+### Deploying Updates (v1.2.0, v1.3.0, etc.)
+
+Create `scripts/deploy.sh` in your project root:
+
+```bash
+#!/bin/bash
+set -e
+
+VERSION=$1
+
+if [ -z "$VERSION" ]; then
+  echo "Usage: ./scripts/deploy.sh v1.2.0"
+  exit 1
+fi
+
+echo "🔨 Building $VERSION..."
+bun run build
+
+echo "📦 Deploying to GitHub Pages..."
+cd dist
+git add .
+git commit -m "Deploy $VERSION" || echo "No changes to commit"
+git push
+
+cd ..
+echo "✅ Deployed to https://kccleoc.github.io/seedpgp-web-app/"
+echo "🏷️  Don't forget to tag: git tag $VERSION && git push --tags"
+```
+
+Make executable and use:
+
+```bash
+chmod +x scripts/deploy.sh
+./scripts/deploy.sh v1.2.0
+```
+
+---
+
+### Repository Structure
+
+- **seedpgp-web** (Private) - Your source code, active development
+- **seedpgp-web-app** (Public) - Built files only, served via GitHub Pages
+
+**Cost: $0/month** ✅
