+### Export a static site
+
+Generate a self-contained static site as a zip archive for air-gapped or offline deployment:
+
+```bash
+mint export
+```
+
+This command builds your documentation, renders every page, and bundles the output with all static assets into a zip file. The archive includes a lightweight Node.js server and launcher scripts for macOS and Windows so anyone can view the docs locally without an internet connection.
+
+By default, the output file is `export.zip`. Use the `--output` flag to specify a custom filename:
+
+```bash
+mint export --output docs.zip
+```
+
+| Flag | Description |
+| --- | --- |
+| `--output` | Set the output zip file path. Defaults to `export.zip`. |
+| `--groups` | Mock user groups for the export. |
+| `--disable-openapi` | Disable OpenAPI file generation during export. |
+
+#### View the exported site
+
+After exporting, unzip the archive and open the docs:

+The docs are served at `http://localhost:3000` by default. Set the `PORT` environment variable to use a different port.

+<Note>
+  Node.js is required on the machine where you view the exported docs. The first time you run `mint export`, an internet connection is needed to download the client. Subsequent exports can run offline.
