+# Data Generator
+
+## Overview
+
+The Data Generator project provides a flexible and customizable way to generate random data for various use cases, such as testing, development, and simulation. The project leverages the [DataFaker](https://github.com/DiUS/java-faker) library to create realistic and diverse datasets. The current implementation includes generators for payment, aviation, StarGate, and StarWars data.
+
+## Features
+
+- Generate realistic data for various domains
+- Easily extendable with new data templates
+- Uses DataFaker for rich and varied data generation
+- Outputs data in JSON format for easy integration
+
+## Local Build
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/skodjob/data-generator.git
+   ```
+2. Navigate to the project directory:
+   ```bash
+   cd data-generator
+   ```
+3. Build the project using Maven:
+   ```bash
+   mvn clean install
+   ```
+
+## Usage
+
+### Include dependency to your maven test project
+```xml
+<dependency>
+    <groupId>io.skodjob</groupId>
+    <artifactId>data-generator</artifactId>
+</dependency>
+```
+
+### Generate Payment Data
+
+To generate payment data, use the `payment_data` template:
+
+```java
+import io.skodjob.datagenerator.DataGenerator;
+import io.skodjob.datagenerator.enums.ETemplateType;
+
+public class Main {
+    public static void main(String[] args) {
+        DataGenerator dataGenerator = new DataGenerator(ETemplateType.PAYMENT_FIAT);
+        String paymentDataString = dataGenerator.generateStringData();
+        JsonNode paymentDataJson = dataGenerator.generateJsonData();
+        System.out.println(paymentDataString);
+    }
+}
+```
+
+### Generate Flight Data
+
+To generate flight data, use the `flights` template:
+
+```java
+import io.skodjob.datagenerator.DataGenerator;
+import io.skodjob.datagenerator.enums.ETemplateType;
+
+public class Main {
+    public static void main(String[] args) {
+        DataGenerator dataGenerator = new DataGenerator(ETemplateType.FLIGHTS);
+        String paymentDataString = dataGenerator.generateStringData();
+        JsonNode paymentDataJson = dataGenerator.generateJsonData();
+        System.out.println(paymentDataString);
+    }
+}
+```
+
+To use different templates just change the input parameter for `DataGenerator` and use it in the same way.
+
+## Templates
+
+The project currently includes the following templates:
+- `payment_data`
+- `flights`
+- `stargate`
+- `starwars`
+- `iot_device`
+- `payroll`
+
+Each template corresponds to a specific data domain and generates JSON data that can be used for various testing and development purposes.
