```

Notice that you can use Markdown inside of the descriptions, for example "login" will be shown in bold (**login**) and "fancy" will be shown in italics (_fancy_).

!!! tip
    You don't have to add metadata for all the tags that you use.

### Use your tags

Use the `tags` parameter with your *path operations* (and `APIRouter`s) to assign them to different tags:

.termynal-comment {
  color: #4a968f;
  font-style: italic;
  display: block;
}

.termy {
  /* For right to left languages */
  direction: ltr;
}

.termy [data-termynal] {
  white-space: pre-wrap;
}

a.external-link {
  /* For right to left languages */
  direction: ltr;
  display: inline-block;
}

a.external-link::after {
  /* \00A0 is a non-breaking space
