+# Karpenter Integration with Cluster API
+
+This document briefly outlines the scope, communication media, and
+stakeholders for a formal Feature Group dedicated to exploring and
+defining how Karpenter can be integrated with Cluster API.
+
+## User Story and Problem Statement
+
+As a Cluster API administrator who uses node autoscaling to manage resource
+in my clusters, I would like to utilize the Karpenter project with Cluster API
+so that I can gain access to its features and capabilities.
+
+At the time of writing, the Cluster API project only officially supports the
+Kubernetes Cluster Autoscaler (CAS)for automatically managing node resources.
+The Karpenter project is an alternative node autoscaler and autoprovisioner
+which has community requested features, such as pod consolidation, that do not
+have equivalents in the CAS. We would like to determine how Cluster API users
+can utilize Karpenter, and if necessary create community supported projects to
+support this activity.
+
+## Scope
+
+The scope of this effort will be the following:
+
+1. Determine what options are available for a consistent Karpenter on Cluster
+   API experience.
+2. Agree upon a path forward to guide the Cluster API community with Karpenter
+   usage.
+
+Depending on the outcome of the 2nd item above, we may choose to keep this
+Feature Group active during the longer term to support Karpenter integration
+design and work efforts in Cluster API, with the blessing of the larger
+Cluster API community.
+
+## Communication
+
+We will meet on [Wednesdays at 11:00 PT (Pacific Time)][zoomMeeting].
+[Convert to your timezone][convert]. Meeting notes will be documented in this
+[HackMD document][agenda]. Meetings will be recorded and posted to the
+[SIG Cluster Lifecycle YouTube playlist][playlist].
+
+Regular, summarized updates of group progress will be provided during weekly
+Cluster API office hours on Wednesdays @ 10:00 PT on [Zoom][zoomMeeting].
+
+Chat with stakeholders on Kubernetes [Slack](http://slack.k8s.io/) in the
+[cluster-api](https://kubernetes.slack.com/archives/C8TSNPY4T) channel.
