 Creates a new `BrowserWindow` with native properties set by the `options`.
 Usually you only need to set the `width` and `height`, other properties will
 have decent default values.
 
+By default the `node-integration` option is `all`, which means node integration
+is available to the main page and all its iframes. You can also set it to
+`except-iframe`, which would disable node integration in all iframes, or
+`manual-enable-iframe`, which is like `except-iframe`, but would enable iframes
+whose name is suffixed by `-enable-node-integration`. And setting to `disable`
+would disable the node integration in both the main page and its iframes.

+An example of enable node integration in iframe with `node-integration` set to
+`manual-enable-iframe`:

+```html
+<!-- iframe with node integration enabled -->
+<iframe name="gh-enable-node-integration" src="https://github.com"></iframe>
+
+<!-- iframe with node integration disabled -->
+<iframe src="http://jandan.net"></iframe>
