+## Preferences
+
+Karpenter is aware of preferences (node affinity, pod affinity, pod anti-affinity, and pod topology) and treats them as requirements in most circumstances. Karpenter uses these preferences when determining if a pod can schedule on a node (absent topology requirements), or when determining if a pod can be shifted to a new node.
+
+Karpenter starts by treating preferred affinities as required affinities when constructing requirements for a pod. When these requirements cannot be met, the pod's preferences are relaxed one-at-a-time by ascending weight (lowest weight is relaxed first), and the remaining requirements are tried again.

+Karpenter does not interpret preferred affinities as required when constructing topology requirements for scheduling to a node. If these preferences are necessary, required affinities should be used [as documented in Node Affinity](#node-affinity).

 You can think of these concepts as `required` and `preferred`, since Kubernetes never implemented other variants of these rules.

 Taints are the opposite of affinity.
 Setting a taint on a node tells the scheduler to not run a pod on it unless the pod has explicitly said it can tolerate that taint. This example shows a NodePool that was set up with a taint for only running pods that require a GPU, such as the following:
