For development purposes we suggest using `yarn link` that will create symlink to @grafana/ui lib. To do so navigate to `packages/grafana-ui` and run `yarn link`. Then, navigate to your project and run `yarn link @grafana/ui` to use the linked version of the lib. To unlink follow the same procedure, but use `yarn unlink` instead.
We've upgraded Storybook to version 6 and with that we will convert to using [controls](https://storybook.js.org/docs/react/essentials/controls) instead of knobs for manipulating components. Controls will not require as much coding as knobs do. Please refer to the [storybook style-guide](https://github.com/grafana/grafana/blob/main/contribute/style-guides/storybook.md#contrls) for further information.
