How to add summary section in extent report dashboard view

[softwaredev999]

Hello,

Env: Eclipse + Maven + testNG + extent report

When I run testNG suite file, how can I add summary section (see image below) in extent report dashboard view? Can you please share some tutorial link for me to try it out?

<?xml version="1.0" encoding="UTF-8"?>
<suite name="SuiteName" parallel="methods">
    <test name="TestName" allow-return-values="true">
        <classes>
            <class name="Simple.Test1" />
            <class name="Simple.Test2" />
            <class name="Complex.Test1C"/>
            <class name="Complex.Test2C" />
            <class name="Parallel.Test1P" />
            <class name="Parallel.Test2P" />
        </classes>
    </test>
</suite>

Thank you!
