 ### Caching packages dependencies
 
-The action has a built-in functionality for caching and restoring npm/yarn dependencies. Supported package managers are `npm`, `yarn`, `pnpm`. The `cache` input is optional, and caching is turned off by default. By default, the action searches for the dependency file in the project root and uses its hash as a part of cache key. Use `cache-dependency-path` to specify custom dependency file path. The field accepts wildcards or an array of files to be cached. 
+The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under hood for caching dependencies but requires less configuration settings.

+Supported package managers are `npm`, `yarn`, `pnpm`. The `cache` input is optional, and caching is turned off by default.
+
+The action defaults to search for the dependency file (`package-lock.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. See the examples of `cache-dependency-path` usage in the [Advanced usage](docs/advanced-usage.md#caching-packages-dependencies) guide.
+
+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.
