 The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under the hood for caching global packages data but requires less configuration settings. Supported package managers are `npm`, `yarn`, `pnpm` (v6.10+). The `cache` input is optional.
 
-Caching is turned on by default when a `packageManager` field is detected in the `package.json` file. The `package-manager-cache` input provides control over this automatic caching behavior. By default, `package-manager-cache` is set to `true`, which enables caching when a valid package manager field is detected in the `package.json` file.
