+# Promote the ubi-nodejs-extension to paketo-buildpacks
+
+## Summary
+
+Promote the the [ubi-nodejs-extension](https://github.com/paketo-community/ubi-nodejs-extension)
+from paketo-community to paketo-buildpacks.
+
+## Motivation 
+
+The ubi-nodejs-extension has been building and releases have been published regularly over the
+last year. There are no outstanding major issues and we've not had to make any substantial
+changes over the last few months and it seems like it's time to be promoted.
+
+In addition, the extension mechanism is no longer experimental.
+
+## Detalied Explanation
+
+## Rational and Alternatives
+
+UBI support was planned and agreed in this rfc -
+[https://github.com/paketo-buildpacks/rfcs/blob/main/text/0056-ubi-based-stacks.md?](https://github.com/paketo-buildpacks/rfcs/blob/main/text/0056-ubi-based-stacks.md) 
+
+Promotion of the ubi-nodejs-extension is a step towards completing this and the ubi-nodejs-extension
+is ready and actively maintained with no major open issues and regular releases.
+
+The alternative is to leave the ubi-nodejs-extension in paketo-community to bake for a while longer
+
+## Implementation
+
+* Move the paketo-community/ubi-nodejs-extension repo to `paketo-buildpacks/ubi-nodejs-extension`
+* Fixup and changes needed in the automation scripts, etc.
+* Update references in the paketo-buildpackes/nodejs meta buildpack to point to
+  `paketo-buildpacks/ubi-nodejs-extension`.
