 Use labels to target an issue or a PR for a given release, add `help wanted` to good issues for new community members, and `blocker` for issues that scare you or need immediate attention. Request for more information from a submitter if an issue is not clear. Create new labels as needed by the project.
 
+### Backports
+
+The Github workflow in [backport.yml](.github/workflows/backport.yml) creates backport PRs automatically when the original PR with an appropriate label `backport <backport-branch-name>` is merged to main. To backport a PR to `1.x`, add a label `backport 1.x` to the PR, once this PR is merged to main, the workflow will create a backport PR to the `1.x` branch.

 Respond to enhancement requests, and forum posts. Allocate time to reviewing and commenting on issues and conversations as they come in.

 ## Welcome!
 
 **[opensearch-js](https://www.npmjs.com/package/@opensearch-project/opensearch)** is [a community-driven, open source fork](https://aws.amazon.com/blogs/opensource/introducing-opensearch/) of elasticsearch-js licensed under the [Apache v2.0 License](LICENSE.txt). For more information, see [opensearch.org](https://opensearch.org/).
 
 ## Example use
+
 The OpenSearch JavaScript client provides a safer and easier way to interact with your OpenSearch cluster. Rather than using OpenSearch from the browser and potentially exposing your data to the public, you can build an OpenSearch client that takes care of sending requests to your cluster.
 
 The client contains a library of APIs that let you perform different operations on your cluster and return a standard response body. The example here demonstrates some basic operations like creating an index, adding documents, and searching your data.

 ### Setup
