+We are looking for packagers to expand the OKDerator catalog! The [Directory](directory.md)
+lists the operators we would like to offer and which ones still need an owner. Pick one that
+interests you, or bring your own suggestion to the `#okd-dev` Slack channel or the OKD
+Operators Working Group.

+## How packaging works
+
+Two repositories make up the project:
+
+- [okd-operator-pipeline](https://github.com/okd-project/okd-operator-pipeline) builds the
+  operator images and OLM bundles from the upstream sources, applying patches where an
+  operator needs changes to run on OKD.
+- [okderators-catalog-index](https://github.com/okd-project/okderators-catalog-index) is the
+  file-based catalog that clusters consume, with a release branch per OKD version.
+
+Most contributions start in the pipeline repository - its
+[CONTRIBUTING.md](https://github.com/okd-project/okd-operator-pipeline/blob/main/CONTRIBUTING.md)
+explains how to add a new operator, and
+[BUILDING.md](https://github.com/okd-project/okd-operator-pipeline/blob/main/BUILDING.md)
+covers building and testing against your own registry. For a walkthrough of the development
+process, see the
+[OKD Operator Development Overview](https://www.youtube.com/watch?v=_uUNnUWQQ9E) video.
+
+## Other ways to help
+
+Not everything needs a new operator. You can also:
+
+- test packaged operators on your cluster and report issues
+- update an existing operator to a newer upstream release
+- fill gaps in the [Directory](directory.md) - upstream sources and packaging notes
