 We should be able to run Dashboards now changing back to its base directory and running `yarn start`. Navigating to the URL given as console output (something like `http://localhost:5601/omf`) you should now be able to log in with user `admin` and password `admin`.
 
+To run selenium based integration tests, download and export the firefox web-driver to your PATH. Also, run `node scripts/build_opensearch_dashboards_platform_plugins.js` or `yarn start` before running the tests. This is essential to generate the bundles.
