+### Operator Glasspane
+
+The local operator cockpit lives in [`scripts/glass.sh`](scripts/glass.sh).
+On a root/platform install it uses the tmux session name `glasspane`. On a
+tenant install it uses `<tenant>-glasspane`.
+
+```sh
+# create and attach
+sh scripts/glass.sh
+
+# create without attaching (safe smoke test)
+GLASS_ATTACH=0 sh scripts/glass.sh
+
+# remove the glasspane session
+sh scripts/glass.sh kill
+```
+
+On FreeBSD, keep `fd-find` installed. It provides the `fd` command that `pi`
+expects inside the glasspane session.
+
