+migrate: Introduce `skuba migrate node-version` to automatically upgrade a project's Node.js version
+
+`skuba migrate node-version` will attempt to automatically upgrade projects to Node.js 20.
+It will look in the project root for Dockerfiles, `.nvmrc`, and Serverless files,
+as well as CDK files in `infra/`, and try to upgrade them to a Node.js 20 version.
+
+Other Node.js versions can be specified with `skuba migrate node-version <version>`.
+
+skuba might not be able to upgrade all projects, so please check your project for any files that skuba missed. It's
+possible that skuba will modify a file incorrectly, in which case please
+[open an issue](https://github.com/seek-oss/skuba/issues/new).
+
+Node.js 20 comes with its own breaking changes, so please read the [Node.js 20 release notes](https://nodejs.org/en/blog/announcements/v20-release-announce) alongside the skuba release notes. In addition,
+
+- For AWS Lambda runtime updates to `nodejs20.x`, consider reading the [release announcement](https://aws.amazon.com/blogs/compute/node-js-20-x-runtime-now-available-in-aws-lambda/) as there are some breaking changes with this upgrade.
+- You may need to upgrade your versions of CDK and Serverless as appropriate to support nodejs20.x.
