+# Inventory Project
+
+## Description
+
+The Inventory project is a web application built with Node.js and Express.js. It's designed to manage and track inventory items. This application allows users to add, view, edit, and delete items in the inventory.
+
+## Prerequisites
+
+-   Node.js (v18 or later)
+-   npm (comes with Node.js)
+-   PostgreSQL (version 13 or later)
+
+## Setup
+
+1.  **Clone the repository:**
+```
+bash
+    git clone <repository-url>
+    cd inventory
+    
+```
+2.  **Install dependencies:**
+```
+bash
+    npm install
+    
+```
+3.  **Set up the database:**
+    -   Ensure you have PostgreSQL running.
+    -   Create a database named `inventory_db` (or you can name it whatever you want and update the `config.js` file).
+    -   Update the database connection details in `src/config.js`.
+    -   Run the database setup script:
+```
+bash
+        node src/db/setupDb.js
+        
+```
+This will create the table and insert some sample data.
