+# Lab3 Project
+
+This project is a small web application built using Java Servlets and JSP with Spring Boot framework. Maven is used for dependency management and project build.
+As Spring boot framework already contains TomCat Server, no more further download needed.
+
+## Prerequisites
+
+Before you begin, ensure you have the following installed on your machine:
+
+- Java Development Kit (JDK) 8 or later
+- Apache Maven
+- Your favorite Java IDE or text editor
+
+## Getting Started
+
+To get started with this project, follow these steps:
+
+1. Clone or download this repository to your local machine.
+
+2. Navigate to the project directory.
+
+3. Build the project using Maven:
+
+```bash
+mvn clean package
+
+```
+This command will compile the source code, run tests, and package everything into a JAR file located in the target/ directory.
+
+4. Run the application
+```bash
+mvn spring-boot:run
+```
+
+5. Once the application is running, open your web browser and visit http://localhost:8080 to view the application.
