+## Deploying JupyterGIS with JupyterLite
+
+You can run JupyterGIS entirely in the browser using **JupyterLite**.
+
+1. **Create a repository** using the [xeus-lite-demo](https://github.com/jupyterlite/xeus-lite-demo) template.
+2. In your fork, edit `environment.yml` and add:
+   ```yaml
+   - jupytergis-lite
+   ```
+3. **Add your data and jGIS files** under the `content/` directory of your repository.
+   These files will be available directly inside your Lite deployment.
+4. **Enable GitHub Pages** under _Settings → Pages_ for your repository.
+5. Once the build completes, your Lite deployment will be live at:
+   ```
+   https://<username>.github.io/<repo-name>/
+   ```
+
+This provides a lightweight, fully browser-based JupyterGIS environment — no server required.
+
+> [!IMPORTANT]
+> Collaboration is **not yet supported** in JupyterLite static deployments.
