-# Release please reusable workflows
+# 🚀 Release Please Reusable Workflows
 
-This is the reusable workflow for release any project.
+This documentation explains how to configure and use the reusable **release-please** workflow in your projects. For further details on **release-please**, please refer to the [release-please GitHub page](https://github.com/googleapis/release-please).
 
-## Secrets
+## 1. Configuration Files
 
-### application_id
+### 1.1. release-please-config.json
 
-**Required** The application id to use to log app in to GitHub.
+This file, placed at the root of your project, defines the schema, customizes the changelog sections, and sets the release type rules for your package(s). For example, in a Node.js project:
 
-### private_key
+```json
+{
+  "$schema": "https://raw.githubusercontent.com/googleapis/release-please/main/schemas/config.json",
+  "changelog-sections": [
+    { "type": "feat", "section": "🚀 Features", "hidden": false },
+    { "type": "change", "section": "🚀 Features", "hidden": false },
+    { "type": "deprecate", "section": "⚠️ Changes", "hidden": false },
+    { "type": "remove", "section": "⚠️ Changes", "hidden": false },
+    { "type": "fix", "section": "🐞 Bug Fixes", "hidden": false },
+    { "type": "revert", "section": "🐞 Bug Fixes", "hidden": false },
+    { "type": "security", "section": "🐞 Bug Fixes", "hidden": false },
+    { "type": "perf", "section": "✨ Polish", "hidden": false },
+    { "type": "refactor", "section": "✨ Polish", "hidden": false },
+    { "type": "style", "section": "✨ Polish", "hidden": false },
+    { "type": "build", "section": "🧰 Other", "hidden": false },
+    { "type": "chore", "section": "🧰 Other", "hidden": false },
+    { "type": "deps", "section": "🧰 Other", "hidden": true },
+    { "type": "ci", "section": "🧰 Other", "hidden": true },
+    { "type": "test", "section": "🧪 Tests", "hidden": false },
+    { "type": "docs", "section": "📚 Documentation", "hidden": true }
+  ],
+  "packages": {
+    ".": {
+      "release-type": "node",
+      "changelog-path": "CHANGELOG.md"
+    }
+  }
+}
+```
 
-**Required** The private key to use to log app in to GitHub.
+### 1.2. .release-please-manifest.json
 
+This file tracks the published versions by **release-please**. You can start with it empty if your project has no version yet, or pre-fill it with versions if necessary.
 
-## Example usage
+*Empty initialization:*
+
+```json
+{}
+```
+
+*Or with predefined versions:*
+
+```json
+{
+  "packages": {
+    ".": {
+      "version": "1.0.0"
+    }
+  }
+}
+```
+
+## 2. ⚙️ Usage in Your Repository
+
+Place the following YAML file (e.g., `.github/workflows/release.yml`) in your repository to directly call the reusable workflow. It triggers the workflow on a push to the `main` branch, applies the necessary permissions, and inherits secrets.
 
 ```yaml
-uses: iExecBlockchainComputing/github-actions-workflows/release-please@release-please-v1.0.0
-secrets: 
-  application_id: ${{ secrets.application_id }}
-  private_key: ${{ secrets.private_key }}
-```
+on:
+  push:
+    branches:
+      - main
+
+permissions:
+  contents: write
+  issues: write
+  pull-requests: write
+
+name: release-please
+
+jobs:
+  release-please:
+    uses: iExecBlockchainComputing/github-actions-workflows/.github/workflows/release-please.yml@release-please-v2.0.0
+    secrets: inherit
+```
+
+## 3. Release Types
+
+**release-please** supports different release types tailored for various ecosystems and languages via the `release-type` parameter in the configuration file. Here are some of the common ones:
+
+- **node**  
+  For Node.js projects, it automatically manages changelogs and bump versions following semver conventions.
+
+- **java**  
+  For Java projects, applying specific rules for Maven, Gradle, and other build tools.
+
+- **python**  
+  For Python projects, it follows versioning conventions commonly used in the Python ecosystem.
+
+- **ruby**, **go**, **dotnet**  
+  Additional types are available based on the nature of your project.
+
+> For more detailed information on each release type and additional configuration options, please visit the [release-please documentation](https://github.com/googleapis/release-please?tab=readme-ov-file#strategy-language-types-supported).
+
+## 4. Use Cases: Single Project vs. Monorepo
+
+### 4.1. Single Project
+
+For a single project, the entire configuration and version tracking are managed for one package:
+
+- **Configuration:**  
+  The `release-please-config.json` file contains the global settings, and the `.release-please-manifest.json` file tracks the unique version.
+
+- **Workflow:**  
+  The YAML file located in `.github/workflows/release.yml` triggers the release process for the entire project.
+
+### 4.2. Monorepo (Multiple Projects)
+
+For a monorepo containing several projects, the configuration allows you to manage each package independently:
+
+- **Configuration:**  
+  In the `release-please-config.json` file, you can define multiple packages under the `"packages"` key. For example, if your monorepo contains a primary package and a subproject named `subproject`:
+
+  ```json
+  {
+    "$schema": "https://raw.githubusercontent.com/googleapis/release-please/main/schemas/config.json",
+    "changelog-sections": [
+      { "type": "feat", "section": "🚀 Features", "hidden": false },
+      { "type": "fix", "section": "🐞 Bug Fixes", "hidden": false },
+      { "type": "docs", "section": "📚 Documentation", "hidden": true },
+      ...
+    ],
+    "packages": {
+      ".": {
+        "release-type": "node",
+        "changelog-path": "CHANGELOG.md"
+      },
+      "subproject": {
+        "release-type": "node",
+        "changelog-path": "subproject/CHANGELOG.md"
+      }
+    }
+  }
+  ```
+
+- **Manifest:**  
+  The `.release-please-manifest.json` file can maintain separate entries for each package:
+
+  ```json
+  {
+    "packages": {
+      ".": {
+        "version": "1.0.0"
+      },
+      "subproject": {
+        "version": "0.9.0"
+      }
+    }
+  }
+  ```
+
+- **Workflow:**  
+  The YAML workflow file remains the same, triggering the release process for all defined packages according to the configuration.
