 ## Node version file
 
-The `node-version-file` input accepts a path to a file containing the version of Node.js to be used by a project, for example `.nvmrc`, `.node-version`, `.tool-versions`, or `package.json`. If both the `node-version` and the `node-version-file` inputs are provided then the `node-version` input is used.
+The `node-version-file` input accepts a path to a file containing the version of Node.js to be used by a project, for example `.nvmrc`, `.node-version`, `.tool-versions`, `package.json`, or an action metadata file such as `action.yml`. For action metadata, the action reads the Node.js version from `runs.using` (for example, `node24`). If both the `node-version` and the `node-version-file` inputs are provided then the `node-version` input is used.
 See [supported version syntax](https://github.com/actions/setup-node#supported-version-syntax).
 
 > The action will search for the node version file relative to the repository root.
