-# catalogue (Koha) running in Docker, shown on the kiosk as a public
-# search terminal.
+# catalogue (Koha) running in Docker, with a "Find a book" page on the kiosk.
 #
 # What gets installed (all from this checkout's library/ directory, deployed to
 # $LIBRARY_DIR - see library/README.md for the stack itself):
-#   - Koha: the catalogue ("OPAC", public search, no login) and the staff
-#     interface (cataloguing, Z39.50 lookup, label printing).
-#   - Quick Add: a one-box "scan an ISBN, the book is added" page.
+#   - Koha: cataloguing, Z39.50 lookup, label printing, people and lending.
+#   - Quick Add: the "scan an ISBN, the book is added" page, with a Find a book tab.
 #   - MariaDB.
 # Docker itself is installed on demand (lib/docker.sh).
 #
-# On the kiosk the catalogue is added as one of the Sites (tabs) with
-# duration 0 (stay put - it's a search terminal, not a rotating display).
-# Staff and Quick Add are meant for the librarian's own device; whether they
-# are reachable from the LAN or only from this kiosk is the "Network access"
-# choice below. NOTE: Docker publishes ports straight through iptables and
-# bypasses ufw, so "this kiosk only" is enforced by binding the published
-# ports to 127.0.0.1 (BIND_ADDR in library/.env), not by firewall rules.
+# Everything needs a login. The kiosk shows the "Find a book" page signed in as a
+# READ-ONLY guest login (Find a book is search only; the guest has no Koha account at
+# all, because Koha's own search permission also allows editing label layouts); the page
+# list stores that guest login like any other Basic Auth site. The admin login never
+# goes into the kiosk's config. The public catalogue (OPAC) is off by default.
+#
+# Whether other devices on the LAN can reach the library site is the "Network access"
+# choice below. NOTE: Docker publishes ports straight through iptables and bypasses
+# ufw, so "this kiosk only" is enforced by binding the published ports to 127.0.0.1
+# (BIND_ADDR in library/.env), not by firewall rules.
 #
 # Depends on: lib/menu.sh, lib/config.sh, lib/docker.sh being sourced first.
