+# Development environment deployment with Docker compose
+
+### Deployment details
+
+With [Docker Compose file](../../docker-compose.yml) it's easy to bootstrap the full Fn development stack that includes the following components:
+
+ - MySQL server for database
+ - Redis server for message queue
+ - Fn server with scale group (supported only for Docker Swarm)
+ - Fn UI
+ - Grafana
+ - Prometheus
+
+Given compose file was developed specifically for Fn platform development/testing purpose, it's not a production-ready script. In order to get production deployment please review [Kubernetes deployment instruction](./kubernetes/README.md).
