The default configuration defines two taxonomies, categories and tags.

{{< code-toggle config=taxonomies />}}

When creating a taxonomy:

• Use the singular form for the key (e.g., category).
• Use the plural form for the value (e.g., categories).

Then use the value as the key in front matter:

{{< code-toggle file=content/example.md fm=true >}}

title: Example categories:

• vegetarian
• gluten-free tags:
• appetizer
• main course {{< /code-toggle >}}

If you do not expect to assign more than one term from a given taxonomy to a content page, you may use the singular form for both key and value:

{{< code-toggle file=hugo >}} taxonomies: author: author {{< /code-toggle >}}

Then in front matter:

{{< code-toggle file=content/example.md fm=true >}}

title: Example author:

• Robert Smith {{< /code-toggle >}}

The example above illustrates that even with a single term, the value is still provided as an array.

You must explicitly define the default taxonomies to maintain them when adding a new one:

{{< code-toggle file=hugo >}} taxonomies: author: author category: categories tag: tags {{< /code-toggle >}}

To disable the taxonomy system, use the disableKinds setting in the root of your site configuration to disable the taxonomy and term page kinds.

{{< code-toggle file=hugo >}} disableKinds = ['categories','tags'] {{< /code-toggle >}}

See the taxonomies section for more information.
