 ### 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 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.
