+# Attention Hacktoberfest (MUST READ)
+
+Due to noticeable uptick in spammy pull requests, [originating from Hacktoberfest participants](https://hacktoberfest.digitalocean.com/hacktoberfest-update), the `kubernetes/website` repo has been restricted to contributors who have previously interacted with the Kubernetes org.
+
+The restriction will be evaluated daily as the situation unfolds and ultimately removed once there is a resolution.
+
+**If you are a new contributor**, or have any questions, please chat with us on the `#SIG-Docs` [Slack channel](https://kubernetes.slack.com/messages/sig-docs) ([get an invite for Slack](https://slack.k8s.io/)).
