 # Grafana Experimental
 
+> [!WARNING]
+> As part of our ongoing efforts to improve and streamline our UI components, we are gradually deprecating this repository.\
+> Components previously housed here are being migrated to other UI components packages such as [grafana/ui](https://github.com/grafana/grafana/tree/main/packages/grafana-ui) and [grafana/plugin-ui](https://github.com/grafana/plugin-ui).\
+> Please note that future development and improvements should happen in the respective new locations. We recommend developers to start using and referencing the new packages in their projects.\
+> Thank you for your understanding and cooperation during this transition.

 The main difference between grafana/experimental and grafana/ui is how the components are versioned. Having a separate "experimental" package allows us to release breaking changes when necessary while the grafana/ui package follows a slower-moving policy.
 
 As developers use and test the components and report issues, the maintainers learn more about shortcomings of the components. The older and more used a component is, the less likely it is that new issues will be found and subsequently need to introduce breaking changes.
