+## Build
+
+Run the supplied `build.sh` script with the required environment vars (can
+source `accumolo2.env` file) to pull all dependencies and build the container.
+
+_Note requires Maven and Docker_
+
+Optionally run each command separately to configure the containers tags etc.
+
+## Configure
+
+The container will use the Gaffer Proxy store by default to connect to an
+existing graph and provide a Gremlin endpoint to connect to (see the [Tinkerpop docs](https://tinkerpop.apache.org/docs/current/reference/#connecting-gremlin-server)).
+
+The Gaffer graph the container will connect to can be configured as usual by
+editing the `store.properties` file, which you can also bind mount over on an
+existing image. The config file locations are under the predefined workdir
+set by the parent gremlin server image the key locations in the image are:
+
+- `/opt/gremlin-server/conf/gaffer/store.properties` - Override for custom store properties.
+- `/opt/gremlin-server/conf/gafferpop/gafferpop.properties` - Override to configure the graph.
+
+The configuration for the Gremlin server is provided by the `gaffer-gremlin-server.yaml`
+this again can be modified as needed or bind mounted over. Please see the
+[official Gaffer docs](https://gchq.github.io/gaffer-doc/latest/administration-guide/gaffer-deployment/gremlin/)
+for more information on configuring this image.
+
+## Run
+
+Simply run the container to publish the Gremlin server making sure to make the
+configured port available (port 8182 by default) this can then be connected to
+via the address specified in the server's yaml config to use Gremlin traversal.
+The server can then be connected via the Gremlin console e.g. if using
+`gremlinpython`:
+
+```python
+from gremlin_python.process.anonymous_traversal_source import traversal
+
+g = traversal().withRemote(
+ DriverRemoteConnection('ws://localhost:8182/gremlin', 'g'))
+```
+
+### Demo Deployment
+
+A demo/example using the tinkerpop 'modern' dataset and accumulo backed Gaffer
+is available under the `example` directory. This can be ran using docker compose
+to deploy the containers then, the provided jupiter notebook demonstrates how to
+connect and some basic queries on the data using `gremlinpython`.
+
+Run the example with:
+
+```bash
+docker compose up
+```
