Add the Pulse script to your template engine's layout (EJS, Pug, Handlebars) or serve it via static HTML.
---
## Method 1: EJS template
If you use EJS as your template engine, add the script to your layout with a production guard.
```html filename="views/layout.ejs"
<% if (process.env.NODE_ENV === 'production') { %>
<% } %>
<%= title %>
<%- body %>
```
## Method 2: Static HTML
If you serve static HTML files via Express, add the script directly.
```html filename="public/index.html"
My Express App
Hello World
```
