+# `urunc` Adopters
+
+This is a list of organizations that have publicly shared that they use
+`urunc`. If your organization uses `urunc`, we would love to hear about it.
+Adding yourself to this list helps the project grow and lets others learn from
+your experience.
+
+## Adding your organization
+
+Open a pull request that adds a row to the table below. Please:
+
+- only add an organization you represent. Do not add entries on behalf of
+  others,
+- keep the table in alphabetical order by organization name,
+- pick one of the [adopter types](#adopter-types) listed below,
+- briefly describe how you use `urunc` (e.g. which unikernels or VM/Sandbox
+  monitors, Kubernetes or plain containerd, production or evaluation).
+
+If you prefer not to open a PR, reach out to the maintainers on the
+[Slack channel](https://cloud-native.slack.com/archives/C08V201G35J) or the
+[maintainers' mailing list](mailto:cncf-urunc-maintainers@lists.cncf.io) and we
+will add you.
