+Connection to Spark Cluster on Standalone Mode requires the following set of steps:

+0. Verify that the docker image (check the Dockerfile) and the Spark Cluster which is being deployed, run the same version of Spark. 
+1. [Deploy Spark on Standalone Mode](http://spark.apache.org/docs/latest/spark-standalone.html).
+2. Run the Docker container with `--net=host` in a location that is network addressable by all of your Spark workers. (This is a [Spark networking requirement](http://spark.apache.org/docs/latest/cluster-overview.html#components).)
+    * NOTE: When using `--net=host`, you must also use the flags `--pid=host -e TINI_SUBREAPER=true`. See https://github.com/jupyter/docker-stacks/issues/64 for details.
+3. The language specific instructions are almost same as mentioned above for Mesos, only the master url would now be something like spark://10.10.10.10:7077

 ## Notebook Options
 
 You can pass [Jupyter command line options](http://jupyter.readthedocs.org/en/latest/config.html#command-line-arguments) through the [`start-notebook.sh` command](https://github.com/jupyter/docker-stacks/blob/master/minimal-notebook/start-notebook.sh#L15) when launching the container. For example, to set the base URL of the notebook server you might do the following:
