 {{es}} includes a set of built-in {{ilm-init}} policies that govern how managed indices transition as they age. This guide demonstrates how you can customize the lifecycle of a managed index, to adjust how the index transitions across [data tiers](/manage-data/lifecycle/data-tiers.md) and what [actions](/manage-data/lifecycle/index-lifecycle-management/index-lifecycle.md#ilm-phase-actions), such as downsampling or shrinking, are performed on the index during each lifecycle phase.
 
+Setting a custom {{ilm-init}} policy is useful when you have a specific set of indices, for example a set of Kubernetes logs which can grow to be quite large in volume, for which you don't want to use the default data retention duration and other {{ilm-init}} settings.

+:::::{admonition} Using @custom component templates
+A `@custom` component template allows you to customize the mappings and settings of the managed index templates, without having to override them or their main component templates.
+
+Many {{es}} managed index templates include one or more `@custom` component templates. A `@custom` component template must first be created before it can be used, and its name must exactly match the name specified in the managed index template in order to be applied automatically to indices as they're created.
+
+For example, if you're ingesting OpenTelemetry (OTel) logs, any OTel log data streams and their backing indices are configured by the `logs-otel@template` managed index template. That index template automatically applies settings defined in the `logs@custom` and the `logs-otel@custom` template when they exist.
+
+Go to **Index Management > Index Templates** and select any managed index to view the `@custom` component templates associated with it.

 If you want your {{ilm-init}} changes to apply only to specific indices, you can create a custom index template directly instead of modifying the custom component template. Use the **Index management** page in {{kib}} or the [index template](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-indices-put-index-template) API to create a new template.
