+
+The most flexible webhook GitHub offers is the `workflow_job` webhook, it includes the `runs-on` information in the payload allowing scaling based on runner labels.
+
+This webhook should cover most people's needs, please experiment with this webhook before considering the others.
+

+spec:

+    duration: "30m"
+```
+
+You can configure your GitHub webhook settings to only include `Workflows Job` events, so that it sends us three kinds of `workflow_job` events per a job run.
+
+Each kind has a `status` of `queued`, `in_progress` and `completed`.
+With the above configuration, `actions-runner-controller` adds one runner for a `workflow_job` event whose `status` is `queued`. Similarly, it removes one runner for a `workflow_job` event whose `status` is `completed`.
+
+Beware that a scale-down after a scale-up is deferred until `scaleDownDelaySecondsAfterScaleOut` elapses. Let's say you had configured `scaleDownDelaySecondsAfterScaleOut` of 60 seconds, 2 consequtive workflow jobs will result in immediately adding 2 runners. The 2 runners are removed only after 60 seconds. This basically gives you 60 seconds of a "grace period" that makes it possible for self-hosted runners to immediately run additional workflow jobs enqueued in that 60 seconds.
+
+You must not include `spec.metrics` like `PercentageRunnersBusy` when using this feature, as it is unnecessary. That is, if you've configured the webhook for `workflow_job`, it should be enough for all your scale-out needs.

+To scale from 0 whilst still being able to provision runners as jobs are queued we must use the `HorizontalRunnerAutoscaler` with only certain metric configurations, only the below configurations support scaling from 0 whilst also being able to provision runners as jobs are queued:

+This is due to that `PercentageRunnersBusy`, by its definition, needs one or more GitHub runners that can become `busy` to be able to scale. If there isn't a runner to pick up a job and enter a `busy` state then the controller will never know to provision a runner to begin with as this metric is no knowledge of the jobs queued and is relying using the number of busy runners as a means for calculating the desired replica count.
 
-If and only if HorizontalRunnerAutoscaler is configured to have a secondary metric of `TotalNumberOfQueuedAndInProgressWorkflowRuns` and the controller sees the primary metric of `PercentageRunnersBusy` returned 0 desired replicas, it uses the secondary metric for calculating the desired replicas once again.
+If a HorizontalRunnerAutoscaler is configured with a secondary metric of `TotalNumberOfQueuedAndInProgressWorkflowRuns` then be aware that the controller will check the primary metric of `PercentageRunnersBusy` first and will only use the secondary metric to calculate the desired replica count if the primary metric returns 0 desired replicas.
 
 A correctly configured `TotalNumberOfQueuedAndInProgressWorkflowRuns` can return non-zero desired replicas even when there are no runners other than [registration-only runners](#note-on-scaling-tofrom-0), hence the `PercentageRunnersBusy` + `TotalNumberOfQueuedAndInProgressWorkflowRuns` configuration makes scaling from zero possible.
