 ### Maintainer's Notes
-This repository is provided and maintained by Tailscale, Inc.
-
-The CI script in this repository uses an ephemeral authkey generated for the
-Tailnet owned by TailscaleGitHubActionBot.github. A new ephemeral authkey will
-need to be generated every 3 months and placed in the TAILSCALE\_AUTHKEY in
-the Secrets for this repository.
-
-If a CI run fails, it is likely because the Ephemeral Authkey expired since
-the last time it was run. You should generate a new key.
