+# Docker Guacamole
+
+A Docker Container for [Apache Guacamole](https://guacamole.incubator.apache.org/), a client-less remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH over HTML5.
+
+## Usage
+
+```shell
+docker run \
+  -p 8080:8080 \
+  -v </path/to/config>:/config \
+  oznu/guacamole
+```
+
+## Parameters
+
+The parameters are split into two halves, separated by a colon, the left hand side representing the host and the right the container side.
+
+* `-p 8080:8080` - Binds the service to port 8080 on the Docker host, **required**
+* `-v /config` - The config and database location, **required**
