Import the component and assemble its parts as simple usage:

import { Breadcrumb } from '@vapor-ui/core';

<Breadcrumb.Root>
  <Breadcrumb.Item />
  <Breadcrumb.Separator />
  <Breadcrumb.Ellipsis />
  <Breadcrumb.Separator />
  <Breadcrumb.Item />
</Breadcrumb.Root>

assemble its parts as customized usage:

<Breadcrumb.RootPrimitive>
  <Breadcrumb.ListPrimitive>
    <Breadcrumb.ItemPrimitive>
      <Breadcrumb.LinkPrimitive />
    </Breadcrumb.ItemPrimitive>
    <Breadcrumb.Separator />
    <Breadcrumb.ItemPrimitive>
       <Breadcrumb.EllipsisPrimitive />
    </Breadcrumb.ItemPrimitive>
  </Breadcrumb.ListPrimitive>
