+Given the current major release of 2.0, projects in this organization maintain the following active branches.
 
-* **main**: The next _major_ release. This is the branch where all merges take place and code moves fast.
-* **1.x**: The next _minor_ release. Once a change is merged into `main`, decide whether to backport it to `1.x`.
-* **1.0**: The _current_ release. In between minor releases, only hotfixes (e.g. security) are backported to `1.0`.

 ### Feature Branches
 
-Do not creating branches in the upstream repo, use your fork, for the exception of long lasting feature branches that require active collaboration from multiple developers. Name feature branches `feature/<thing>`. Once the work is merged to `main`, please make sure to delete the feature branch.

 The release process is standard across repositories in this org and is run by a release manager volunteering from amongst [MAINTAINERS](MAINTAINERS.md).
 
-1. Create a tag, e.g. `v2.1.0`, and push it to the GitHub repo.
-1. The [release-drafter.yml](.github/workflows/release-drafter.yml) will be automatically kicked off and is responsible for drafting a new release on GitHub containing release artifacts.
-1. Before creating a draft release, this workflow creates a GitHub issue asking for approval from the [maintainers](MAINTAINERS.md). See sample [issue](https://github.com/gaiksaya/opensearch-java/issues/1). The maintainers need to approve in order to continue the workflow run.
-1. Once a release is drafted [opensearch-java-maven-sign-and-release/](https://build.ci.opensearch.org/job/opensearch-java-maven-sign-and-release/) jenkins workflow is triggered. The artifacts will be automcatically signed and published to maven.
-1. Increment `systemProp.version` in [gradle.properties](gradle.properties) to the next patch release, e.g. `v2.1.1`, commit and push. 
+### Preparing for Release
+
+1. Check out the branch being released, e.g. `2.x`. 
+2. Create a new branch that matches the version number being released, e.g. `2.10.5`.
+3. Ensure `systemProp.version` in [gradle.properties](gradle.properties) matches the version being released.
+4. Replace `## [Unreleased x.y]` with a version number and date, e.g. `## [2.11.0] - 06/20/2024` in [CHANGELOG](CHANGELOG.md).
+5. Commit your changes, create a tag, e.g. `v2.1.0`, and push your changes and the new tag to GitHub.

+An [increment version workflow](.github/workflows/increment-version.yml) will make a pull request to set `systemProp.version` in [gradle.properties](gradle.properties) to the next version.
+
+Add an unreleased section to [CHANGELOG](CHANGELOG.md) in `main` and backport the change to `2.x`.
