 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. To disable this automatic caching, set the `package-manager-cache` input to `false`.

-> If no valid `packageManager` field is detected in the `package.json` file, caching will remain disabled unless explicitly configured.

 The action defaults to search for the dependency file (`package-lock.json`, `npm-shrinkwrap.json` or `yarn.lock`) in the repository root, and uses its hash as a part of the cache key. Use `cache-dependency-path` for cases when multiple dependency files are used, or they are located in different subdirectories.

 ## Caching packages data
 The action follows [actions/cache](https://github.com/actions/cache/blob/main/examples.md#node---npm) guidelines, and caches global cache on the machine instead of `node_modules`, so cache can be reused between different Node.js versions.
 
 **Caching yarn dependencies:**
-Yarn caching handles both yarn versions: 1 or 2.
+Yarn caching handles both Yarn Classic (v1) and Yarn Berry (v2, v3, v4+).
