How to correctly record according to BEM using the example of a menu?

Question

css

Hello! I decided to master the BEM methodology, but I don’t understand something completely. As I understand it, the point is to give each tag an individual class.
You can use the example of a simple menu to show how to write correctly in html and css.
For example, there is a code:

<div class="menu">
    <ul>
      <li><a href=""></a></li>
      <li><a href=""></a></li>
      <li><a href=""></a></li>
    </ul>
  </div>

How to rewrite it in BEM?

    <li class="menu__item"><a class="menu__link" href=""></a></li>
    <li class="menu__item"><a class="menu__link" href=""></a></li>
  </ul>
</nav>
