+# Optional: one-command local Postgres + pgvector for development.
+#
+# If you already have a Postgres + pgvector instance running somewhere
+# (e.g. a managed/remote server you used with the original project), you
+# do NOT need this - just point backend/.env at it instead.
+#
+# Ollama is intentionally NOT included here: install it natively on the
+# host (see docs) so it can use your CPU efficiently without an extra
+# container layer, and so `ollama pull` model files persist outside Docker.
+#
+# Usage:
+#   docker compose up -d
+#   # then in backend/.env: DB_HOST=localhost, DB_PORT=5432, DB_NAME=pgvector,
+#   # DB_USER=postgres, DB_PASSWORD=<the value you set below>
+#
+version: "3.9"
