 This will start Fn in single server mode, using an embedded database and message queue. You can find all the
 configuration options [here](docs/operating/options.md). If you are on Windows, check [here](docs/operating/windows.md).

 ### Your First Function
 
 Functions are small but powerful blocks of code that generally do one simple thing. Forget about monoliths when using functions, just focus on the task that you want the function to perform.

+# 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).
