-
-- Caching is now automatically enabled for npm projects when either the `devEngines.packageManager` field or the top-level `packageManager` field in `package.json` is set to `npm`. For other package managers, such as Yarn and pnpm, caching is disabled by default and must be configured manually using the `cache` input.
-
-- The `always-auth` input has been removed, as it is deprecated and will no longer be supported in future npm releases. To ensure your workflows continue to run without warnings or errors, please remove any references to `always-auth` from your configuration.

-## Breaking changes in V5
-
-- Enabled caching by default with package manager detection if no cache input is provided.
-  > For workflows with elevated privileges or access to sensitive information, we recommend disabling automatic caching by setting `package-manager-cache: false` when caching is not needed for secure operation.

-### Running without a lockfile
-
-If you choose not to use a lockfile, you must ensure that **caching is disabled**. The `cache` feature relies on the lockfile to generate a unique key for the cache entry.
-
-To run without a lockfile:
-1. Do not set the `cache` input.
-2. If your `package.json` contains a `packageManager` field set to npm (or devEngines.packageManager), automatic caching is enabled by default. Override this by setting `package-manager-cache: false`.

 ## Check latest version
 
 The `check-latest` flag defaults to `false`. When set to `false`, the action will first check the local cache for a semver match. If unable to find a specific version in the cache, the action will attempt to download a version of Node.js. It will pull LTS versions from [node-versions releases](https://github.com/actions/node-versions/releases) and on miss or failure will fall back to the previous behavior of downloading directly from [node dist](https://nodejs.org/dist/). Use the default or set `check-latest` to `false` if you prefer stability and if you want to ensure a specific version of Node.js is always used.

 ## 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 Classic (v1) and Yarn Berry (v2, v3, v4+).
-
+Yarn caching handles both yarn versions: 1 or 2.

-## Publishing to npm with Trusted Publisher (OIDC)
-
-npm supports Trusted Publishers, enabling packages to be published from GitHub Actions using OpenID Connect (OIDC) instead of long-lived npm tokens. This improves security by replacing static credentials with short-lived tokens, reducing the risk of credential leakage and simplifying authentication in CI/CD workflows.
-
-### Requirements
-
-Trusted publishing requires a compatible npm version:
-
-* **npm ≥ 11.5.1 (required)**
-* **Node.js 24 or newer (recommended)** — includes a compatible npm version by default
-
-> If npm is below 11.5.1, publishing will fail even if OIDC permissions are correctly configured.
-
-You must also configure a **Trusted Publisher** in npm for your package/scope that matches your GitHub repository and workflow (and optional environment, if used).
-
-### Example workflow
-
-```yaml
-    permissions:
-      contents: read
-      id-token: write  # Required for OIDC
-
-    steps:
-      - uses: actions/checkout@v6
-
-      - uses: actions/setup-node@v6
-        with:
-          node-version: '24'
-          registry-url: 'https://registry.npmjs.org'
-
-      - run: npm ci
-      - run: npm run build --if-present
-      - run: npm publish
-```
-
-> **Note**: If the Trusted Publisher configuration (GitHub owner/repo/workflow file, and optional environment) does not match the workflow run identity exactly, publishing may fail with **E404 Not Found** even if the package exists on npm.
-
-For more details, see the [npm Trusted Publishers documentation](https://docs.npmjs.com/trusted-publishers) and the [GitHub Actions OpenID Connect (OIDC) overview](https://docs.github.com/en/actions/concepts/security/openid-connect).
-
-## Use private mirror
-
-It is possible to use a private mirror hosting Node.js binaries. This mirror must be a full mirror of the official Node.js distribution.
-The mirror URL can be set using the `mirror` input.
-It is possible to specify a token to authenticate with the mirror using the `mirror-token` input.
-The token will be passed in the `Authorization` header.
-
-```yaml
-- uses: actions/setup-node@v6
-  with:
-    node-version: '24.x'
-    mirror: 'https://nodejs.org/dist'
-    mirror-token: 'your-mirror-token'
-```
+### always-auth input
+The always-auth input sets `always-auth=true` in .npmrc file. With this option set [npm](https://docs.npmjs.com/cli/v6/using-npm/config#always-auth)/yarn sends the authentication credentials when making a request to the registries.
