+There are a few steps illustrating how disk autoscaler works:
 
 1. You create an disk autoscaler integration endpoint in your Aiven project setting the maximum additional storage at the same time.
 2. You enable a disk autoscaler integration for your service using the new disk autoscaler integration endpoint.
 3. From that point onward, the evaluation of disk space availability for your service is done every 30 seconds.
-4. When disk storage consumption reaches the treshold for a specific service, disk autoscaler increases available storage space by 10% every time taking the currently-used service plan as a baseline.
