+The parameter `eagerFetch` (optional) indicates that all tasks on the queue will be prefetched.
 If not set or set to false it will only fetch a single task from the queue.
 By fetching all tasks from the queue as they arrive it can give different priorities to all tasks put on the same queue.
 Effectively it will give tasks on the same queue that have fewer tasks running on a worker a higher priority over tasks with more tasks running on a worker.

 Changing the `queueType` configuration parameter if the queues are already created won't work.
 If `queueType` needs to be changed, the queues need to be deleted first.
 
+The parameter `maxWorkersAvailable` (optional) can be set to the maximum number of workers the system can scale to when using automatically scaling of workers.
+This is useful because when worker resources are automatically scaled it can cause issues in combination with a low `maxCapacityUse` parameter.
+For example if worker scaling is based on the percentage workers being used it can mean the system will never scale up because the `maxCapacityUse` for certain input queues will never exceed the scaling threshold percentage.
+Especially when the system runs with a low number of workers the `maxCapacityUse` is easily reached before the scaling threshold is reached.
+By setting `maxWorkersAvailable` the scheduler will determine if tasks already have reached the `maxCapacityUse` value based on the `maxWorkersAvailable` value and not the actual number of workers running.
+It will than schedule tasks beyond the `maxCapacityUse` assuming this would trigger the system to scale up if needed,
+and only for a short amount of time claim more resources for a specific queue than would be allowed by the `maxCapacityUse` percentage.
+When more workers would be available than was configured as `maxWorkersAvailable` the scheduler will assign workers proportionally to the `maxCapacityUse` based on the actual number of workers available.
+
 In `queues` there can be 1 or more queue configurations.
 Each queue configuration consists of 3 parameters:
