+
+## Static Hosting
+
+Since Lightning Decoder is a static site built with Vite, it can be deployed to any static hosting service:
+
+### Build the project
+
+```bash
+npm run build
+```
+
+This creates a `dist/` folder with the production build.
+
+### Deploy the dist folder
+
+Upload the contents of `dist/` to your hosting provider:
+
+- **Netlify**: Drag and drop the `dist/` folder to Netlify's deploy interface
+- **GitHub Pages**: Push the `dist/` contents to a `gh-pages` branch
+- **Cloudflare Pages**: Connect your repository and set the build command to `npm run build` with output directory `dist`
+- **AWS S3 + CloudFront**: Upload `dist/` to an S3 bucket and configure CloudFront for CDN delivery
+
+### Environment Variables
+
+No environment variables are required for the base application. All Lightning Network decoding happens client-side.
+
+## Development
+
+### Local Development
+
+```bash
+npm install
+npm run dev
+```
+
+The app will be available at `http://localhost:5173`
+
+### Storybook
+
+```bash
+npm run storybook
+```
+
+Storybook will be available at `http://localhost:6006`
+
+### Testing
+
+```bash
+npm test
+```
+
+Run the test suite with Vitest.
+
+## Build for Production
+
+```bash
+npm run build
+```
+
+The optimized production build will be in the `dist/` folder.
+
+## Troubleshooting
+
+### Build fails with dependency errors
+
+Make sure you're using Node.js 18 or higher:
+
+```bash
+node --version
+```
+
+If you need to upgrade Node.js, use a version manager like nvm.
+
+### Storybook not loading
+
+Clear the Storybook cache:
+
+```bash
+rm -rf node_modules/.cache/storybook
+npm run storybook
+```
+
+### Tests failing
+
+Make sure all dependencies are installed:
+
+```bash
+npm install
+npm test
+```
