-# Example: add OpenConcho's web UI to a self-hosted Honcho Docker Compose stack.
+# Run OpenConcho's web UI with `docker compose up`.
 #
-# Drop this `openconcho` service into the Compose project that already runs your
-# Honcho `api` service. nginx proxies /v3 and /health to the API, so the browser
-# makes same-origin requests and never hits CORS.
+# Standalone: serves the SPA on http://localhost:8080 and reverse-proxies the
+# Honcho API under the same origin (no browser CORS). By default it points at a
+# Honcho running on the host at :8000 — override HONCHO_UPSTREAM for anything else:
+#
+#   HONCHO_UPSTREAM=https://honcho.example.net docker compose up
+#
+# To fold this into an existing Honcho Compose stack, drop the `openconcho`
+# service into that project, set HONCHO_UPSTREAM to the api service
+# (e.g. http://api:8000), and add `depends_on: { api: { condition: service_healthy } }`.
