+Nothing to see here really.
+
+Usage
+-----
+
+This is an Ansible playbook; it's very non-generic and heavily customized to
+how my machines are set up.
+The primary usage scenario is going to this repository's Actions and running
+the workflow.
+
+You can also run it manually; first, install the Ansible Galaxy dependencies:
+
+    make deps
+
+Make sure you can SSH to the hosts as the `maintenance` user; then, you can run
+the playbook:
+
+    make run
+
+Reboot everything:
+
+    make reboot
+
+Reboot my cloud servers only:
+
+    make reboot/cloud
