+### Default Instance Warming
+
+You can use the default instance warmup feature to improve the Amazon CloudWatch metrics used for dynamic scaling. 
+When default instance warmup is not enabled, each instance starts contributing usage data to the aggregated metrics 
+as soon as the instance reaches the InService state. However, if you enable default instance warmup, this lets 
+your instances finish warming up before they contribute the usage data.
+
+To optimize the performance of scaling policies that scale continuously, such as target tracking and step scaling 
+policies, we strongly recommend that you enable the default instance warmup, even if its value is set to 0 seconds. 
+
+To set up Default Instance Warming for an autoscaling group, simply pass it in as a prop
+
+```ts
+declare const vpc: ec2.Vpc;
+declare const instanceType: ec2.InstanceType;
+declare const machineImage: ec2.IMachineImage;
+
+
+new autoscaling.AutoScalingGroup(this, 'ASG', {
+  vpc,
+  instanceType,
+  machineImage,
+
+  // ...
+
+  defaultInstanceWarmup: Duration.seconds(5),
+});
+```
