+## Control Provisioning with Labels
+
+The [Provisioner CRD]({{< ref "provisioner-crd.md" >}}) supports defining
+node properties like instance type and zone.For certain well-known labels (documented below), Karpenter will provision
+nodes accordingly. For example, in response to a label of
+`topology.kubernetes.io/zone=us-east-1c`, Karpenter will provision nodes in
+that availability zone.
+
+### Instance Types
+
+Karpenter supports specifying [AWS instance type](https://aws.amazon.com/ec2/instance-types/).
+
+The default value includes all instance types with the exclusion of metal
+(non-virtualized),
+[non-HVM](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/virtualization_types.html),
+and GPU instances.
+
+If necessary, Karpenter supports defining a limited list of default instance types.
+
+If more than one type is listed, Karpenter will determine the
+instance type to minimize the number of new nodes.
+
+View the full list of instance types with `aws ec2 describe-instance-types`.
+
+**Example**
+
+*Set Default with provisioner.yaml*
+
+```yaml
+spec:
+  instanceTypes:
+    - m5.large
+```
+
+*Override with workload manifest (e.g., pod)*
+
+```yaml
+spec:
+  template:
+    spec:
+      nodeSelector:
+        node.kubernetes.io/instance-type: m5.large
+```
+
+### Availability Zones
+
+`topology.kubernetes.io/zone=us-east-1c`
+
+- key: `topology.kubernetes.io/zone`
+- value example: `us-east-1c`
+- value list: `aws ec2 describe-availability-zones --region <region-name>`
+
+Karpenter can be configured to create nodes in a particular zone. Note that the Availability Zone us-east-1a for your AWS account might not have the same location as us-east-1a for another AWS account.

+IDs.](https://docs.aws.amazon.com/ram/latest/userguide/working-with-az-ids.html)
+
+### Capacity Type
+
+- key: `node.k8s.aws/capacity-type`
+- values
+  - `on-demand` (default)
+  - `spot`
+
+Karpenter supports specifying capacity type and defaults to on-demand.
+
+Specify this value on the provisioner to enable spot instances. [Spot
+instances](https://aws.amazon.com/ec2/spot/) may be preempted, and should not
+be used for critical workloads.
+
+**Example**
+
+*Set Default with provisioner.yaml*
+
+```yaml
+spec:
+  labels:
+    node.k8s.aws/capacity-type: spot
+```
+
+*Override with workload manifest (e.g., pod)*
+
+```yaml
+spec:
+  template:
+    spec:
+      nodeSelector:
+        node.k8s.aws/capacity-type: spot
+```
+
+### Architecture
+
+- key: `kubernetes.io/arch`
+- values
+  - `amd64` (default)
+  - `arm64`
+
+Karpenter supports `amd64` nodes, and `arm64` nodes.
+
+**Example**
+
+*Set Default with provisioner.yaml*
+
+```yaml
+spec:
+  labels:
+    kubernetes.io/arch: arm64
+```
+
+*Override with workload manifest (e.g., pod)*
+
+```yaml
+spec:
+  template:
+    spec:
+      nodeSelector:
+        kubernetes.io/arch: amd64
+```
+
+### Operating System
+
+- key: `kubernetes.io/os`
+- values
+  - `linux` (default)
+
+At this time, Karpenter only supports Linux OS nodes.
+
+### Accelerators, GPU
+
+Accelerator (e.g., GPU) values include
+- `nvidia.com/gpu`
+- `amd.com/gpu`
+- `aws.amazon.com/neuron`
+
+Karpenter supports accelerators, such as GPUs.
+
+To enable instances with accelerators, use the [instance type
+well known label selector](#instance-types).
+
+Additionally, include a resource requirement in the workload manifest. Thus,
+accelerator dependent pod will be scheduled onto the appropriate node.
+
+*accelerator resource in workload manifest (e.g., pod)*
+
+```yaml
+spec:
+  template:
+    spec:
+      containers:
+      - resources:
+          limits:
+            nvidia.com/gpu: "1"
+```
