+[![Deploy to Docker Cloud](https://files.cloud.docker.com/images/deploy-to-dockercloud.svg)](https://cloud.docker.com/stack/deploy/?repo=https://github.com/luccioman/yacy_search_server/tree/docker/docker)
+
+## Getting built image from Docker Hub
+
+	docker pull luccioman/yacy
+	
+Repository URL : (https://hub.docker.com/r/luccioman/yacy/)
+
+## Building image yourself
+
+Using yacy_search_server/docker/Dockerfile :
+
+	cd yacy_search_server/docker
+	docker build .
+	
+## Default admin account
+
+login : admin
+
+password : docker
+
+You should modify this default password with page /ConfigAccounts_p.html when exposing publicly your YaCy container.
+
+## Usage
+
+### First start
+
+#### Most basic
+
+	docker run luccioman/yacy
+
+YaCy web interface is then exposed at http://[container_ip]:8090.	
+You can retrieve the container IP address with `docker inspect`.
+
+#### Easier to handle
+
+	docker run --name yacy -p 8090:8090 luccioman/yacy
+	
+--name option allow easier management of your container (without it, docker automatically generate a new name at each startup).
+
+-p option map host port and container port, allowing web interface access through the usual http://localhost:8090.
+
+#### With persistent data volume
+
+	docker run -v [your_host/data/directory]:/opt/yacy_search_server/DATA luccioman/yacy
+		
+This allow your container to reuse a data directory form the host.
+
+#### As background process
+
+	docker run -d luccioman/yacy
+
+### Next starts
+
+#### As attached process
+
+	docker start -a yacy
+	
+#### As background process
+
+	docker start yacy
+
+### Shutdown
+
+* Use "Shutdown" button in administration web interface
