-Before we can use a `Taxonomy` method, we need to capture a `Taxonomy` object.
-
-## Capture a taxonomy object
-
-Consider this site configuration:
-
-{{< code-toggle file=hugo >}}
-[taxonomies]
-genre = 'genres'
-author = 'authors'
-{{< /code-toggle >}}
-
-And this content structure:
-
-```text
-content/
-├── books/
-│   ├── and-then-there-were-none.md --> genres: suspense
-│   ├── death-on-the-nile.md        --> genres: suspense
-│   └── jamaica-inn.md              --> genres: suspense, romance
-│   └── pride-and-prejudice.md      --> genres: romance
-└── _index.md
-```
-
-To capture the "genres" taxonomy object from within any template, use the [`Taxonomies`] method on a `Site` object.
-
-```go-html-template
-{{ $taxonomyObject := .Site.Taxonomies.genres }}
-```
-
-To capture the "genres" taxonomy object when rendering its page with a taxonomy template, use the [`Terms`] method on the page's [`Data`] object:
-
-{{< code file=layouts/_default/taxonomy.html  >}}
-{{ $taxonomyObject := .Data.Terms }}
-{{< /code >}}
-
-To inspect the data structure:
-
-```go-html-template
-<pre>{{ jsonify (dict "indent" "  ") $taxonomyObject }}</pre>
-```
-
-Although the [`Alphabetical`] and [`ByCount`] methods provide a better data structure for ranging through the taxonomy, you can render the weighted pages by term directly from the `Taxonomy` object:
-
-```go-html-template
-{{ range $term, $weightedPages := $taxonomyObject }}
-  <h2><a href="{{ .Page.RelPermalink }}">{{ .Page.LinkTitle }}</a></h2>
-  <ul>
-    {{ range $weightedPages }}
-      <li><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></li>
-    {{ end }}
-  </ul>
-{{ end }}
-```
-
-In the example above, the first anchor element is a link to the term page.

-An ordered taxonomy is a slice, where each element is an object that contains the term and a slice of its weighted pages.
-
-Each element of the slice provides these methods:
-
-Count
-: (`int`) Returns the number of pages to which the term is assigned.
-
-Page
-: (`page.Page`) Returns the term's `Page` object, useful for linking to the term page.
-
-Pages
-: (`page.Pages`) Returns a `Pages` object containing the `Page` objects to which the term is assigned, sorted by [taxonomic weight]. To sort or group, use any of the [methods] available to the `Pages` object. For example, sort by the last modification date.
-
-Term
-: (`string`) Returns the term name.
-
-WeightedPages
-: (`page.WeightedPages`) Returns a slice of weighted pages to which the term is assigned, sorted by [taxonomic weight]. The `Pages` method above is more flexible, allowing you to sort and group.
