-The package manager `pnpm` is not pre-installed in [GitHub Actions runner images](https://github.com/actions/runner-images) (unlike `npm` and `yarn`) and so it must be installed in a separate workflow step (see below). If the action finds a `pnpm-lock.yaml` file, it uses the [pnpm](https://pnpm.io/cli/install) command `pnpm install --frozen-lockfile` by default to install dependencies.

+### Package manager cache disable
+
+When the action installs dependencies,
+it caches the package manager cache from npm or from Yarn 1 (Classic) by default,
+based on the [lockfile](#package-manager-cache) it discovers.
+If package manager caching is implemented separately from the action,
+for example to work with Yarn Modern or pnpm,
+then disable the actions' package manager caching by setting the parameter
+`package-manager-cache` to `false`.
+
+GitHub's [actions/setup-node](https://github.com/actions/setup-node/blob/main/README.md) offers a convenient way to install a chosen version of Node.js
+and to set up caching of package manager caches in one step.

 ### Custom cache key
 
 Sometimes the default cache key does not work. For example, if you cannot share the Node modules across Node versions due to native extensions. In that case pass your own `cache-key` parameter.
