+# Deploy your site
+
+Docusaurus is a **static-site-generator** (also called **[Jamstack](https://jamstack.org/)**).
+
+It builds your site as simple **static HTML, JavaScript and CSS files**.
+
+## Build your site
+
+Build your site **for production**:
+
+```bash
+npm run build
+```
+
+The static files are generated in the `build` folder.
+
+## Deploy your site
+
+Test your production build locally:
+
+```bash
+npm run serve
+```
+
+The `build` folder is now served at `http://localhost:3000/`.
+
+You can now deploy the `build` folder **almost anywhere** easily, **for free** or very small cost (read the **[Deployment Guide](https://docusaurus.io/docs/deployment)**).
