 You define a node’s roles by setting `node.roles` in [`elasticsearch.yml`](../../deploy/self-managed/configure-elasticsearch.md). If you set `node.roles`, the node is only assigned the roles you specify. If you don’t set `node.roles`, the node is assigned the following roles:

-This module provides per-index settings to control the allocation of shards to nodes:
+In Elasticsearch, per-index settings allow you to control the allocation of shards to nodes through index-level shard allocation settings. These settings enable you to specify preferences or constraints for where shards of a particular index should reside. This includes allocating shards to nodes with specific attributes or avoiding certain nodes. This level of control helps optimize resource utilization, balance load, and ensure data redundancy and availability according to your deployment's specific requirements. In addition to the content in this article, there are additional resources:
