-## Sequence-to-Sequence Tutorial with Github Issues Data
-Code For Medium Article: ["How To Create Data Products That Are Magical Using Sequence-to-Sequence Models"](https://medium.com/@hamelhusain/how-to-create-data-products-that-are-magical-using-sequence-to-sequence-models-703f86a231f8)
+# [WIP] End-to-End kubeflow tutorial using a Sequence-to-Sequence model
 
-## Resources:
+This example demonstrates how you can use `kubeflow` end-to-end to train and
+serve a Sequence-to-Sequence model on an existing kubernetes cluster. This
+tutorial is based upon @hamelsmu's article ["How To Create Data Products That
+Are Magical Using Sequence-to-Sequence
+Models"](https://medium.com/@hamelhusain/how-to-create-data-products-that-are-magical-using-sequence-to-sequence-models-703f86a231f8).
 
-1. [Tutorial Notebook](https://nbviewer.jupyter.org/github/hamelsmu/Seq2Seq_Tutorial/blob/master/notebooks/Tutorial.ipynb):  The Jupyter notebook that coincides with the Medium post.
+## Goals
 
-2. [seq2seq_utils.py](./notebooks/seq2seq_utils.py):  convenience functions that are used in the tutorial notebook to make predictions.
+There are two primary goals for this tutorial:
 
-3. [ktext](https://github.com/hamelsmu/ktext): this library is used in the tutorial to clean data.  This library can be installed with `pip`.  
+*   End-to-End kubeflow example
+*   End-to-End Sequence-to-Sequence model
 
-4. [Nvidia Docker Container](https://hub.docker.com/r/hamelsmu/seq2seq_tutorial/): contains all libraries that are required to run the tutorial.  This container is built with Nvidia-Docker v1.0.  You can run this container by executing `nvidia-docker run hamelsmu/seq2seq_tutorial/` after installing **Nvidia-Docker v1.0.** Note: I have not tested this on Nvidia-Docker v2.0.
+By the end of this tutorial, you should learn how to:
 
+*   Setup a Kubeflow cluster on an existing Kubernetes deployment
+*   Spawn up a Jupyter Notebook on the cluster
+*   Spawn up a shared-persistent storage across the cluster to store large
+    datasets
+*   Train a Sequence-to-Sequence model using TensorFlow on the cluster using
+    GPUs
+*   Serve the model using TensorFlow Serving
+
+## Steps:

+1.  [Teardown](teardown.md)

+# Setup Kubeflow
+
+In this part, you will setup kubeflow on an existing kubernetes cluster.
+
+## Requirements
+
+*   A kubernetes cluster
+*   `kubectl` CLI pointing to the kubernetes cluster
+    *   Make sure that you can run `kubectl get nodes` from your terminal
+        successfully
+*   The ksonnet CLI: [ks](https://ksonnet.io/#get-started)
+
+Refer to the [user
+guide](https://github.com/kubeflow/kubeflow/blob/master/user_guide.md) for
+instructions on how to setup Kubeflow on your Kubernetes Cluster. Specifically
+complete the [Deploy
+Kubeflow](https://github.com/kubeflow/kubeflow/blob/master/user_guide.md#deploy-kubeflow)
+section and [Bringing up a
+Notebook](https://github.com/kubeflow/kubeflow/blob/master/user_guide.md#bringing-up-a-notebook)
+section.
+
+After completing that, you should have the following ready
+
+*   A ksonnet app in a directory named `my-kubeflow`
+*   An output similar to this for `kubectl get pods`
+
+```
+NAME                              READY     STATUS    RESTARTS   AGE
+ambassador-7987df44b9-4pht8       2/2       Running   0          1m

+ambassador-7987df44b9-qrgsm       2/2       Running   0          1m
+tf-hub-0                          1/1       Running   0          1m
+tf-job-operator-78757955b-qkg7s   1/1       Running   0          1m
+```
+
+*   A Jupyter Notebook accessible at `http://127.0.0.1:8000`
+
+## Provision storage for training data
+
+We need a shared persistent disk to store our training data since containers'
+filesystems are ephemeral and don't have a lot of storage space.
+
+The [Advanced
+Customization](https://github.com/kubeflow/kubeflow/blob/master/user_guide.md#advanced-customization)
+section of the [user
+guide](https://github.com/kubeflow/kubeflow/blob/master/user_guide.md) has
+instructions on how to provision a cluster-wide shared NFS.
+
+For this example, provision a `10GB` NFS mount with the name
+`github-issues-data`.
+
+After the NFS is ready, delete the `tf-hub-0` pod so that it gets recreated and
+picks up the NFS mount. You can delete it by running `kubectl delete pod
+tf-hub-0 -n={NAMESPACE}`
+
+At this point you should have a 10GB mount `/mnt/github-issues-data` in your
+Jupyter Notebook pod. Check this by running `!df` in your Jupyter Notebook.
+
+## Summary
+
+*   We created a ksonnet app for our kubeflow deployment
+*   We created a disk for storing our training data
+*   We deployed the kubeflow-core component to our kubernetes cluster
+*   We connected to JupyterHub and spawned a new Jupyter notebook
+
+Next: [Training the model using our cluster](training_the_model.md)
