+# GSIO-Net Docker Compose Configuration
+# 
+# This file defines a network of GSIO-Net nodes that can communicate with each other.
+# It creates three nodes, each exposing the API on a different host port:
+#   - node1: http://localhost:3001
+#   - node2: http://localhost:3002
+#   - node3: http://localhost:3003
+#
+# Usage:
+#   - Start the network: docker-compose up -d
+#   - View logs: docker-compose logs -f
+#   - Stop the network: docker-compose down
+#   - Stop and remove volumes: docker-compose down -v
