 These instructions assume you are running Docker on a Linux or MacOS host system.
+
+### DNS
+
+To access the Projects created you will need to set up a wildcard DNS entry that points to the `domain` entered in the `etc/flowforge.yml` file.
+
+e.g. assuming that Docker is running on a machine with IP address `192.168.0.8` then an A record point to  `*.example.com`.
+
+This  will mean that any host at `example.com` will resolve to the `192.168.0.8`.
+
+**Note** When testing locally you can not use the loopback address `127.0.0.1` for this, e.g. in the `/etc/hosts` file, as this will resolve to the TCP/IP stack inside each container.
+
+## Installing FlowFuse
+
+### Building Containers
+
+To build the required containers simply run `./build-containers.sh`.
+
+This will build and tag `flowfuse/forge-docker` and `flowfuse/node-red` and `flowfuse/file-server`.
+
+#### flowfuse/flowforge-docker
+
+This container holds the FlowFuse App and the Docker Driver.
+
+#### flowfuse/node-red
+
+This is a basic Node-RED image with the FlowFuse Launcher and the required Node-RED plugins to talk to the FlowFuse Platform.
+
+This is the container you can customize for your deployment.
+
+#### flowfuse/file-server
+
+This holds the Object Store used to allow persistent file storage for Projects running on Docker
+
+## Configuration
+
+Configuration details are stored in the `etc/flowforge.yml` file which is mapped into the `flowforge/forge-docker` container. You will need to edit this file to update the `domain` and `base_url` entries to match the DNS settings.
+
+You also need to update the `VIRTUAL_HOST` entry in the `docker-compose.yml` file to use the same domain as in the `etc/flowforge.yml` file.
+
+You should also update the `email` section to point to a local SMTP server so you can invite users to join teams. 
+
+### Creating Instance
+
+Once the container have been built you can start the FlowFuse by running:
+
+```
+docker-compose -p flowforge up -d
+```
