1. Open Eclipse and right click on your Java project, select "Properties"

2. Select "Java Build Path" and go to the "Libraries" tab as shown below.

3. Select the already available JRE library and click on "Edit" button present on right side. You will see one more new windows called "Edit Library" as shown below.

A. Before we start integrating ReportNG you will need three libraries as follows.

1. reportng-1.1.4.jar
2. velocity-dep-1.4.jar
3. guice-3.0.jar

1. Either download above three libraries and add manually to your class-path (in your eclipse or whatever IDE you will be using for your testing).
   
2. Or add dependencies in Maven "pom.xml" file as shown below and build the project. I am not going to explain how maven works... I am assuming that whoever will be using 2nd option would know maven (this is the recommend option).

    <dependency>
        <groupId>org.uncommons</groupId>
        <artifactId>reportng</artifactId>
        <version>1.1.4</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>com.google.inject</groupId>
        <artifactId>guice</artifactId>
        <version>3.0</version>
    </dependency>
