To use icons in our template you need to install Heroicons - svg icons by Tailwind CSS makers.
Installation:
npm install @heroicons/react
Usage
Now to use the icons - you have to import icons individually to use them.
import { ChartPieIcon } from '@heroicons/react/solid';
function MyComponent() {
  return (
    <div>
      <ChartPieIcon className="h-6 w-6 text-black-500" />
      <p>...</p>
    </div>
  )
}
