+
+# Docker Spotweb image
+
+An image running [ubuntu/15.10](https://github.com/gliderlabs/docker-alpine) Linux and [Spotweb](https://github.com/spotweb/spotweb) (media branch).
+
+This image was mainly for own use, but it seems to be populair so I decided to provide some documentation.
+
+## MySQL
+
+You need a seperate MySQL / MariaDB server. This can be a ofcourse be a (linked) docker container but also a dedicated database server.
+
+## Updates
+
+The container will try to auto-update the database when a newer version image is  released.
+
+## Usage
+
 	docker run --restart=always -d -p 80:80 \
 		--hostname=spotweb \
 		--name=spotweb \
-		-v /config:/config \
+		-v <hostdir_where_config_will_persistently_be_stored>:/config \
+		-e TZ='Europe/Amsterdam'
 		-e SPOTWEB_DB_TYPE=pdo_mysql \
-		-e SPOTWEB_DB_HOST=<hostname> \
+		-e SPOTWEB_DB_HOST=<database_server_hostname> \
 		-e SPOTWEB_DB_NAME=spotweb \
 		-e SPOTWEB_DB_USER=spotweb \
 		-e SPOTWEB_DB_PASS=spotweb \
-		jgeusebroek/spotweb
+		jgeusebroek/spotweb
+
+You should now be able to reach the spotweb interface on port 80, and you can configure Spotweb.
