+# Micto Service

-go-micro 实践模版
+This is the Micto service
+
+Generated with
+
+```
+micro new micto-t --namespace=go.micro --type=srv
+```
+
+## Getting Started
+
+- [Configuration](#configuration)
+- [Dependencies](#dependencies)
+- [Usage](#usage)
+
+## Configuration
+
+- FQDN: go.micro.srv.micto
+- Type: srv
+- Alias: micto
+
+## Dependencies
+
+Micro services depend on service discovery. The default is multicast DNS, a zeroconf system.
+
+In the event you need a resilient multi-host setup we recommend consul.
+
+```
+# install consul
+brew install consul
+
+# run consul
+consul agent -dev
+```
+
+## Usage
+
+A Makefile is included for convenience
+
+Build the binary
+
+```
+make build
+```
+
+Run the service
+```
+./micto-srv
+```
+
+Build a docker image
+```
+make docker
