+
+## Installation Instructions
+
+To run the Expense Tracker application, follow these steps:
+
+1. Clone the project repository to your local machine.
+
+2. Install the required Maven dependencies for the backend. In the project directory, run:
+   
+3. Run the backend Spring application to start the server.
+
+4. For the frontend, navigate to the `web` directory and run:
+
+```bash
+npm install
+```
+
+```bash
+npm run dev
+```
