  items:
    - question: "Which Hugo version does this theme require?"
      answer: |
        Hugo 0.158.0 or later, extended edition.
        Older releases are missing template functions the theme relies on.
    - question: "Do I have to use npm to install the theme?"
      answer: "No. You can install it as an npm package, a Hugo Module, or a git submodule."
    - question: "How do I enable structured data?"
      answer: "Add the matching block to your site params or page front matter. Each block drives one partial, and omitting a block simply omits that schema."

# Structured Data Demo

This page exists to exercise the page-level JSON-LD partials that ship with the
theme, so their output is validated on every build rather than only when a real
site happens to configure them.

Four schemas are emitted from the front matter above:

- **[Product](https://schema.org/Product)** — via `product:`
- **[SoftwareApplication](https://schema.org/SoftwareApplication)** — via `softwareApplication:`
- **[FAQPage](https://schema.org/FAQPage)** — via `faq:`
- **[DefinedTermSet](https://schema.org/DefinedTermSet)** — via `definedTermSet:`

The site-level schemas (`WebSite`, `Organization`, `LocalBusiness` and `Event`)
are configured in `config/_default/params.toml` and render on the home page.

View source on this page to inspect the generated `application/ld+json` blocks,
or paste the URL into the
[Rich Results Test](https://search.google.com/test/rich-results).

## Theme Glossary

### Partial

A template fragment the theme reuses across layouts. Each JSON-LD block on this
page comes from one.

### Front Matter

The metadata block at the top of a content file, which is where every
page-level schema on this page is configured.

### Structured Data

Machine-readable markup, here JSON-LD, that states what a page is about
in a vocabulary search engines read.

It is emitted from front matter, so a page declares what it is once.

#### JSON-LD

The serialisation this theme emits: a script block of JSON, kept apart from the
markup it describes.
