+# CLI: Open Page Option (Multiple)
+
+```console
+npm run webpack-dev-server -- --open-page example1.html,example2.html
+```
+
+Some applications may consist of multiple pages. During development it may
+be useful to directly open multiple pages at the same time. The pages to open
+may be specified as the argument to the `open-page` option.
+
+## What Should Happen
+
+The script should open `http://localhost:8080/example1.html` and
+`http://localhost:8080/example2.html` in your default browser.
+You should see the text on the page itself change to read `Success!`.
