+## Capacity providers
+
+Capacity providers are associated with an Amazon ECS cluster and are used to manage compute capacity for your workloads.
+
+### Create a capacity provider for Amazon ECS Managed Instances
+
+By default, Amazon ECS provides a capacity provider that automatically selects the most cost-optimized general-purpose instace types. However, you can create custom capacity providers to specify instance requirements such as instance types, CPU manufacturers, accelerator types, and other requirements. You can use the following template to create a capacity provider for Amazon ECS Managed Instances that satisfies the specied memory and CPU requirements.
