 This GitHub repository uses a dedicated "test" Tailscale account to authenticate Tailscale during CI runs.
 Each Docker container creates a new authorized machine in that test account.
-The machines are manually cleaned up every so often.
+The machines are authorized with [ephemeral auth keys][] and are automatically cleaned up within 48 hours.
 
 If you are interested in contributing to this repository, you must create a [Tailscale account][] and generate a [Node Authorization auth key][auth key].
