+# Custom MS Office Preview
+
+## Overview
+This module allows users to preview Microsoft Office files (such as Word, Excel, and PowerPoint) directly within the Odoo interface using the Microsoft Online Viewer. It extends the attachment model to recognize Office file types and provides a seamless viewing experience by embedding the Office Viewer in the file preview interface.
+

+    git clone https://github.com/quodoo/odoo_addons.git
+    ```
+2. Update your Odoo configuration file to include the new module directory.
+3. Restart the Odoo server.

+
+## Usage

+2. Open the attachment to preview it using the Microsoft Online Viewer.
+
+## Configuration

+
+## Technical Details
+- **Controller**: Handles the public URL for previewing attachments.
+- **JavaScript**: Patches the attachment model to recognize Office file types and generate the appropriate preview URL.
+- **XML**: Extends the file viewer templates to embed the Microsoft Online Viewer.
