 ## How to Use This Reusable Workflow 🔄
 
-1. **Save the Workflow File**  
-   Place this YAML file (e.g., `publish-npm.yml`) in the `.github/workflows/` directory of your repository. 💾
+### With Trusted Publishers (preferred)
+
+> ⚠️ this method uses npm >= 11.5.1 ensure your project supports a compatible version of npm if not please use the method with npm token.
+
+1. **Call the Reusable Workflow**
+
+   In another workflow file (e.g., triggered by a release), invoke this reusable workflow like so:
+
+   ```yaml
+   name: Call Publish Package NPM Workflow
+   on:
+     release:
+       types: [published]
+
+   permissions:
+     id-token: write # Required for OIDC
+     packages: write
+     contents: read
+
+   jobs:
+     publish:
+       uses: iExecBlockchainComputing/github-actions-workflows/.github/workflows/publish-npm.yml@main
+       with:
+         node-version: "22"
+         build-command: "npm run build:prod"
+         run-tests: true
+         test-command: "npm run test:ci"
+         lint-command: "npm run lint"
+         type-check-command: "npm run check-types"
+         format-check-command: "npm run check-format"
+         # Optional: Download an artifact before building
+         # artifact-name: 'my-build-artifact'
+         # artifact-path: './dist'
+   ```
+
+2. **Configure Trusted Publisher on NPM**
+
+   On [npmjs.com](https://www.npmjs.com/), configure the root publish workflow of your GitHub repository as a trusted publisher for your package.
+   ![trusted publisher](trusted-publisher.png)
+
+   NB: You can have only one trusted publisher per package, if you need multiple publication triggers (workflow_dispatch, release, etc.), you need to merge them into a single workflow referenced as trusted publisher.
