+For npm, cache files are stored in `~/.npm` on Posix, or `~\AppData\npm-cache` on Windows, but it's possible to use `npm config get cache` to find the path on any platform. See https://docs.npmjs.com/cli/cache#cache for more details.
 
 If using `npm config` to retrieve the cache directory, ensure you run [actions/setup-node](https://github.com/actions/setup-node) first to ensure your `npm` version is correct.
 
 >Note: It is not recommended to cache `node_modules`, as it can break across Node versions and won't work with `npm ci`
