+# PDP Metadata Generator
+
+## Overview
+It is recommended to import product metadata into Edge Delivery so that it can be rendered server-side on product detail pages.
+This is important so social media sites which do not parse JavaScript can pick it up.
+
+This project is designed to fetch product data from a catalog service, process it, and generate a metadata spreadsheet in XLSX format which can be used for the https://www.aem.live/docs/bulk-metadata feature in Edge Delivery. 
+
+## Prerequisites
+- Node.js installed on your machine.
+- Access to the catalog service with the necessary API keys and configuration.
+
+## Installation
+1. Clone the repository to your local machine.
+2. Navigate to the project directory.
+3. Run `npm install` to install the dependencies.
+
+## Configuration
+Before running the application, you need to ensure the `configFile` variable in `pdp-metadata.js` points to the correct configuration JSON file URL. This file contains the required parameters to access Catalog Service and should have been setup as part of your project onboarding.
+
+## Running the Application
+To start the application, run the following command in the terminal:
+
+```bash
+npm start
+```
+
+This will fetch the product data, process it, and generate a file named `metadata.xlsx` in the project directory.
