+# Node Feature Discovery
+
+Welcome to Node Feature Discovery -- a Kubernetes add-on for detecting hardware
+features and system configuration!
+
+Continue to:
+
+- **[Introduction](get-started/introduction.md)** for more details on the
+  project.
+
+- **[Quick start](get-started/quick-start.md)** for quick step-by-step
+  instructions on how to get NFD running on your cluster.
+
+## Quick-start -- the short-short version
+
+```bash
+$ kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/node-feature-discovery/master/nfd-master.yaml.template
+  namespace/node-feature-discovery created
+...

+$ kubectl -n node-feature-discovery get all

+# Quick Start
+
+Minimal steps to deploy latest released version of NFD in your cluster.
+
+## Installation
+
+Deploy nfd-master -- creates a new namespace, service and required RBAC rules
+
+```bash
+kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/node-feature-discovery/master/nfd-master.yaml.template
+```
+
+Deploy nfd-worker as a daemonset
+
+```bash
+kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/node-feature-discovery/master/nfd-worker-daemonset.yaml.template
+```
+
+## Verify
+
+Wait until NFD master and worker are running.
+
+```bash
+$ kubectl -n node-feature-discovery get ds,deploy
+NAME                        DESIRED   CURRENT   READY   UP-TO-DATE   AVAILABLE   NODE SELECTOR   AGE
+daemonset.apps/nfd-worker   3         3         3       3            3           <none>          5s
+NAME                         READY   UP-TO-DATE   AVAILABLE   AGE
+deployment.apps/nfd-master   1/1     1            1           17s
+```
+
+Check that NFD feature labels have been created
+
+```bash
+$ kubectl get no -o json | jq .items[].metadata.labels
+{
+  "beta.kubernetes.io/arch": "amd64",
+  "beta.kubernetes.io/os": "linux",
+  "feature.node.kubernetes.io/cpu-cpuid.ADX": "true",
+  "feature.node.kubernetes.io/cpu-cpuid.AESNI": "true",
+  "feature.node.kubernetes.io/cpu-cpuid.AVX": "true",
+...
+```
+
+## Use Node Labels
+
+Create a pod targeting a distinguishing feature (select a valid feature from
+the list printed on the previous step)
+
+```bash
+$ cat << EOF | kubectl apply -f -
+apiVersion: v1
+kind: Pod
+metadata:
+  name: feature-dependent-pod
+spec:
+  containers:
+  - image: k8s.gcr.io/pause
+    name: pause
+  nodeSelector:
+    # Select a valid feature
+    feature.node.kubernetes.io/cpu-cpuid.AESNI: 'true'
+EOF
+pod/feature-dependent-pod created
+```
+
+See that the pod is running on a desired node
+
+```bash
+$ kubectl get po feature-dependent-pod -o wide
+NAME                    READY   STATUS    RESTARTS   AGE   IP          NODE     NOMINATED NODE   READINESS GATES
+feature-dependent-pod   1/1     Running   0          23s   10.36.0.4   node-2   <none>           <none>
+```
