Hi, I need to make some change in kibana css but every time to reflect that changes, I need to delete optimize/bundle folder and restart kibana. Please let me know if there is any other workaround. Thanks, Seema ---

Hey @seema are you running Kibana from our source you cloned from [GitHub](https://github.com/elastic/kibana)? If you are, check out the [Contributing Guide section on setting up your Development Environment](https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md#setting-up-your-development-environment) specifically the `yarn start` command, this will let you iterate a lot quicker by doing incremental rebuilds when it notices that files have changed. ---

Thanks for your reply Brandon. I tried to followed the steps and install Yarn as well but while running command yarn kbn bootstrap it is showing me Command "kbn" not found error. Please let me know further process. ---

Is your source up to date with `master`? The `kbn` tool was just recently added. ---
