How to implement process indicator in Salesforce lightning component?

Hi,

A lightning:progressIndicator component displays a horizontal list of steps in a process, indicating the number of steps in a given process, the current step, as well as prior steps completed. For example, Sales Path uses a progress indicator to guide sales reps through the stages of the sales process.

<aura:component>
    <lightning:progressIndicator currentStep="3" type="base" hasError="true" variant="base">
        <lightning:progressStep label="Step 1" value="1"/>
        <lightning:progressStep label="Step 2" value="2"/>
        <lightning:progressStep label="Step 3" value="3"/>
        <lightning:progressStep label="Step 4" value="4"/>
    </lightning:progressIndicator>
</aura:component>
