+# About the deployment procedure:
+#   We use Docker Compose to build images and launch containers for various services
+#   that make up our software suite:
+#     - sparkd
+#     - TODO: pubsub
+#     - TODO: md-publisher
+#     - TODO: webapp (DSQA on the web)
+#     - TODO: api-server (websocket based)
+#   From inside a devcontainer, you can launch all services in separate containers
+#   on your machine by running:
+#
+#     tools/deploy.sh
+#
+#   This script builds release versions for each service, packaged (generally) in
+#   self-contained directories. Next, it runs a few "docker compose" commands to
+#   build docker images loaded with the self-contained binaries from the previous
+#   step, and start containers with those images to run each service. To view the
+#   commands that deploy.sh runs internally (without actually running them), run:
+#
+#     tools/deploy.sh --dry-run
+#
+#   For additional information/help, run:
