+# Demo: hello world
+
+Steps:
+
+ 1. Clone an existing configuration as a [base].
+ 1. Customize it.
+
+First define a place to work:
+
+<!-- @makeWorkplace @testE2EAgainstLatestRelease-->
+```
+DEMO_HOME=$(mktemp -d)
+```
+
+Alternatively, use
+
+> ```
+> DEMO_HOME=~/hello
+> ```
+
+## Establish the base
+
+Let's run the [hello] service.
+
+To keep this document shorter, the base resources are
+off in a supplemental data directory rather than
+declared here as HERE documents.  Download them:
+
+<!-- @downloadBase @testE2EAgainstLatestRelease-->
+```
+BASE=$DEMO_HOME/base
+mkdir -p $BASE
+
+curl -s -o "$BASE/#1.yaml" "https://raw.githubusercontent.com\
+/kubernetes-sigs/kustomize\
+/master/examples/alphaTestExamples/helloWorld\
+/{configMap,deployment,grouping,kustomization,service}.yaml"
+```
+
+### The Base Kustomization
+
+The `base` directory has a [kustomization] file:
+
+<!-- @showKustomization @testE2EAgainstLatestRelease -->
+```
+more $BASE/kustomization.yaml
+```
+
+### Customize the base
+
+A first customization step could be to change the _app
+label_ applied to all resources:
+
+<!-- @addLabel @testE2EAgainstLatestRelease -->
+```
+sed -i.bak 's/app: hello/app: my-hello/' \
+    $BASE/kustomization.yaml
+```
+
+To do end to end tests using kustomize, go through the following section. You should have GOPATH set up and "kind" installed(https://github.com/kubernetes-sigs/kind).
+
+<!-- @setGoBin @testE2EAgainstLatestRelease -->
+```
+MYGOBIN=$GOPATH/bin
+```
+
+Delete any existing kind cluster and create a new one. By default the name of the cluster is "kind"
+<!-- @deleteAndCreateKindCluster @testE2EAgainstLatestRelease -->
+```
+kind delete cluster;
+kind create cluster;
+```
+
+Use the kustomize binary in MYGOBIN to apply a deployment, fetch the status and verify the status.
+<!-- @e2eTestUsingKustomize @testE2EAgainstLatestRelease -->
+```
+export KUSTOMIZE_ENABLE_ALPHA_COMMANDS=true
+
+$MYGOBIN/kustomize resources apply $BASE --status;
+
+status=$(mktemp);
+$MYGOBIN/resource status fetch $BASE > $status
+
+test 1 == \
+  $(grep "the-deployment" $status | grep "Deployment is available. Replicas: 3" | wc -l); \
+  echo $?
+
+test 1 == \
+  $(grep "the-map" $status | grep "Resource is always ready" | wc -l); \
+  echo $?
+
+test 1 == \
+  $(grep "the-service" $status | grep "Service is ready" | wc -l); \
+  echo $?
+```
+
+Clean-up the cluster 
+<!-- @createKindCluster @testE2EAgainstLatestRelease -->
+```
+kind delete cluster;
+```
