+
+{product-title} is a Kubernetes-native system that manages quotas and how jobs consume them. Kueue decides when a job waits, when a job is admitted to start by creating pods, and when a job should be _preempted_ (active pods should be deleted).
+
+Kueue is compatible with environments that use heterogeneous, elastic resources. This means that the environment has many different resource types, and those resources are capable of dynamic scaling.

+// Personas
+[id="about-kueue-personas"]
+== {kueue-s} personas
+
+Different personas exist in a {kueue-s} workflow.
+
+Batch administrators:: manage the cluster infrastructure and establish quotas and queues.
+Batch users:: runs workloads. Examples of batch users might be researchers, AI/ML engineers, or data scientists.
+Serving users:: runs workloads, for example, to expose a trained AI/ML model for inference.
+Platform developers:: integrates Kueue with other software. Might contribute to the upstream Kueue project.
+
+// How it works
+[id="about-kueue-workflow"]
+== {kueue-s} workflow
+// TODO: add diagram?
+
+The {kueue-s} workflow can be described at a high level as follows:
+
+. Batch administrators create and configure resource flavors and queues.
+. User personas create jobs on the cluster.
+. The `kube-apiserver` component validates and accepts job data.
+. Kueue admits jobs based on configured options, such as order or quota.
+. The job controller creates pods.
+. The `kube-scheduler` component assigns pods to a node in the cluster.
+. The `cluster-autoscaler` component provisions more nodes as required.
