 # Caddy API gateway demo
 Use caddy as microservice API gateway in docker swarm.
 
-## RUN
+## Requirements
+* Docker Engine 1.13+
+* docker-compose 1.11.2+
+
+## Notice
+The image in docker-compose is build by Dockerfile.app and Dockerfile.gateway in this demo.
+I've host it in docker hub, so you can use it in next step.
+You can also build the image by yourself, then don't forget to change the image name in docker-compose.yml
+
+## Run Server
+Pull images from docker hub:
+```bash
+docker-compose pull
+```
+Run
 ```bash
 docker stack deploy -c docker-compose.yml caddy
 ```
 
-## TRY
-visit http://{your-host-ip}:2015  
+## Try
+Because of caddy's proxy connection reuse feature, you can't test this demo by 
+visit http://{your-host-ip}:2015  in your browser.
+I write a client to send concurrent requests.  
+If you have go env, 
+```bash
+cd client
+go run main.go
 ```
-Hello, world! I am 72ec231a5eba :)
-
-Hello, world! I am c1a1bc3e79a1 :)
-
-Hello, world! I am 3e4f9f63c1a0 :)
+You can also use unix shell version:
+```bash
+sh test.sh
 ```
 app will tell you which container it is running in.
