 - The scale down lambda is still active, and should only remove orphan instances. But there is no strict check in place. So ensure you configure the `minimum_running_time_in_minutes` to a value that is high enough to got your runner booted and connected to avoid it got terminated before executing a job.
 - The messages sent from the webhook lambda to scale-up lambda are by default delayed delayed by SQS, to give available runners to option to start the job before the decision is made to scale more runners. For ephemeral runners there is no need to wait. Set `delay_webhook_event` to `0`.
-- All events on the queue will lead to a new runner crated by the lambda. By setting `enable_job_queued_check` to `true` you can enforce only create a runner if the event has a correlated queued job. Setting this can avoid creating useless runners, for example whn jobs got cancelled before a runner is created. We suggest to use this in combination with a pool.
+- All events on the queue will lead to a new runner created by the lambda. By setting `enable_job_queued_check` to `true` you can enforce only create a runner if the event has a correlated queued job. Setting this can avoid creating useless runners, for example when jobs got cancelled before a runner is created or if the job was already picked up by another runner. We suggest to use this in combination with a pool.
 - To ensure runners are created in the same order GitHub sends the events we use by default a FIFO queue, this is mainly relevant for repo level runners. For ephemeral runners you can set `enable_fifo_build_queue` to `false`.
 - Error related to scaling should be retried via SQS. You can configure `job_queue_retention_in_seconds` `redrive_build_queue` to tune the behavior. We have no mechanism to avoid events will never processed, which means potential no runner could be created and the job in GitHub can time out in 6 hours.
