 If you have a Twitter account you would like us to mention, please let us know in the PR or in another manner.
 
+#### Integration releases
+
+You can invoke the release flow by calling `yarn release` from the package root.
+
+There are three parameters which can be passed to this script, one required and two optional.
+
+- __Required__: `--workspace <workspace name>`. eg: `--workspace @langchain/core` (always appended as the first flag when running `yarn release`)
+- __Optional__: `--version <version number>` eg: `--version 1.0.8`. Defaults to adding one to the patch version.
+- __Optional__: `--bump-deps` eg `--bump-deps` Will find all packages in the repo which depend on this workspace and checkout a new branch, update the dep version, run yarn install, commit & push to new branch.
+- __Optional__: `--tag <tag>` eg `--tag beta` Add a tag to the NPM release.
+- __Optional__: `--inc <inc>` eg `--inc patch` The semver increment to apply to the version. Can be one of `major`, `minor`, `patch`, `premajor`, `preminor`, `prepatch`, or `prerelease`. Defaults to `patch`.
+
+This script automatically bumps the package version, creates a new release branch with the changes, pushes the branch to GitHub, uses `release-it` to automatically release to NPM, and more depending on the flags passed.
+
+Halfway through this script, you'll be prompted to enter an NPM OTP (typically from an authenticator app). This value is not stored anywhere and is only used to authenticate the NPM release.
+
+Full example: `yarn release @langchain/core --version 2.0.0 --bump-deps --tag beta --inc major`.
