+# PrestaShop Developer Docs — Claude Context
+
+## Project
+
+Hugo static site. Source is Markdown with YAML front matter. Built with the [Hugo Relearn theme](https://mcshelby.github.io/hugo-theme-relearn/). Deployed at https://devdocs.prestashop-project.org/.
+
+Each major PrestaShop version has its own branch (`8.x`, `9.x`, …). This file lives on the `9.x` branch — all content paths are prefixed with `/9/`. If you are working on another branch, update the version prefix accordingly.
+
+## Hugo Conventions
+
+### Front matter (required on every page)
+
+```yaml
+---
+title: Page Title         # Required. Displayed as heading and in nav.
+menuTitle: Short Title    # Optional. Shorter title for the sidebar.
+weight: 10                # Required. Controls ordering (lower = higher).
+chapter: true             # Optional. Section landing pages only.
+showOnHomepage: true      # Optional. Shows on the docs home page.
+useMermaid: true          # Optional. Only when page uses Mermaid diagrams.
+aliases:                  # Optional. Hugo redirect aliases (see Redirects below).
+  - /9/old/path
+---
+```
+
+### Shortcodes
+
+```
+{{% notice note %}}        → Supplementary information
+{{% notice info %}}        → Important contextual information
+{{% notice tip %}}         → Best practice or recommendation
+{{% notice warning %}}     → Breaking change, deprecation, common pitfall
+{{% children /%}}          → Auto-list child pages (section landing pages)
+{{< relref "/9/..." >}}    → Internal cross-reference — always use relref, never raw paths
+{{< minver v="9.1" >}}     → Minimum version badge
+```
+
+### Images
+
+Stored in `img/` relative to the section. From a depth-1 page (e.g. `themes/concepts/page.md`) the path is `../../img/filename.png`. From depth-2 (e.g. `themes/concepts/templates/page.md`) it is `../../../img/filename.png`.
+
+### Internal links
+
+Always use `{{< relref "/9/section/page" >}}`. Never use relative paths.
+
+## Redirects
+
+When a page is moved or renamed, add an `aliases` key to the **new page's** front matter. Hugo generates a redirect HTML file at the old path automatically.
+
+```yaml
+aliases:
+  - /9/section/old/path/to/page
+```
+
+Multiple aliases are supported as a list. Use the full path from root including `/9/`.
+
+**Do not remove aliases once added** — external sites and search engines may link to old URLs.
+
+## Writing Style
+
+- Present tense, active voice, second person ("you").
+- "must" for requirements, "should" for recommendations, "can" for options.
+- No emojis. No marketing language. No merchant-facing guidance.
+- Lead with the most important information (inverted pyramid).
+- One concept per page when possible.
+- Audience: theme developers and module developers. Not merchants.
+
+## No Duplicate Content
+
+Each concept must live in exactly one place. If two pages need to cover the same information, the second page links to the first — it does not repeat the content.
+
+- Do not copy explanations, code examples, or configuration tables across pages
+- Do not summarize a page's content on another page — link to it instead
+- If you find duplicated content during an edit, remove it from the less authoritative page and add a link

+|-----------|---------|
+| `getting-started/` | Fast path: requirements, quick start, environment setup |
+| `concepts/` | Generic PrestaShop theme system mechanics (any theme) |
+| `hummingbird/` | Reference theme implementation (self-contained) |

+- `concepts/` = mechanics that apply to **any** PrestaShop theme
+- `hummingbird/` = Hummingbird-specific implementation details
+- Cross-reference between the two with "For Hummingbird specifics, see..." / "For how the API works, see..."
+
+## Documentation guidelines
+
+### Technology stack
+
+- **Hummingbird** is the reference theme. Always use it as the example implementation.
+- **Bootstrap 5.3** — not Bootstrap 4. Never document BS4 patterns as current.
+- **BEM** naming convention for CSS classes. Do not mention RSCSS.
+- **Smarty 4** template engine. Use `{extends}` / `{block}` inheritance, not `{include}` patterns.
+- **No jQuery** in theme code. jQuery is loaded by `core.js` for module backward compatibility only. New theme code must use vanilla JavaScript.
+- **`data-ps-*` attributes** for JavaScript DOM hooks — not `.js-` prefixed classes.
+- **Web Platform Baseline** as the browser compatibility reference — not fixed version numbers.
+- **Accessibility (EAA / WCAG 2.2 AA)** is a hard requirement, not optional.
+
+### What not to document
+
+- Classic theme directory structure or code examples
+- `_dev/` folder (Classic-specific build artifact)
+- Bourbon, RSCSS, or any deprecated CSS methodology
+- jQuery usage patterns for new code
+- Fixed browser version lists (e.g. "Chrome 90+")
+- PHP coding standards — those belong in core contribution docs
+- PrestaShop 1.6 or 1.7 patterns unless explaining a migration path
+- Merchant-facing guidance — audience is theme and module developers only
+
+`reference/` pages contain no narrative — pure lookup tables only. All explanatory content belongs in `concepts/` or `hummingbird/`.

+Starting from PrestaShop 9.1, **[Hummingbird]({{< relref "/9/themes/hummingbird" >}})** is the default theme. It is built on Bootstrap 5.3, follows BEM conventions, and provides an accessibility-first, jQuery-free architecture.

+
+| Page | Description |
+|------|-------------|
+| [Theme structure]({{< relref "/9/themes/concepts/theme-structure" >}}) | Directory layout, `theme.yml` reference, core assets |
+| [Templates]({{< relref "/9/themes/concepts/templates" >}}) | Layouts, inheritance, listing pages, head, notifications |
+| [Asset management]({{< relref "/9/themes/concepts/asset-management" >}}) | CSS/JS registration API, per-page assets, module integration |
+| [Hooks]({{< relref "/9/themes/concepts/hooks" >}}) | Extension points for modules in the front office |
+| [Overrides]({{< relref "/9/themes/concepts/overrides" >}}) | Module template/asset overrides and JS selector overrides |
+| [Translation]({{< relref "/9/themes/concepts/translation" >}}) | Internationalization for theme wordings |
+| [RTL support]({{< relref "/9/themes/concepts/rtl" >}}) | Right-to-left language stylesheet handling |
