+Next, you'll want to export a few environment variables. You'll need a Github API token and if you don't already have one, you can get one [here](https://github.com/settings/tokens)

+$ export NAMESPACE=kubeflow

+It's recommended to install the core Kubeflow infrastructure, which includes the ability to train models with a TFJob CRD. In addition to that, we are going to go ahead and add in the Pachyderm and Seldon components:

+```
+$ ks registry add kubeflow github.com/katacoda/kubeflow-ksonnet/tree/master/kubeflow
+$ ks pkg install kubeflow/core
+$ ks pkg install kubeflow/seldon
+$ ks pkg install kubeflow/pachyderm
+```

 ## 2. Deploy Pachyderm and Seldon on top of KubeFlow
 
 We will be using Pachyderm and Seldon for data storage, versioning, pipelining, and serving. We already added these components to our ksonnet app, we just need to deploy/prep them for use.
