+# Demo extra fields
+
+## About
+
+This module demonstrates how to use **native extra fields** (custom fields) in PrestaShop (9.2+ ?).
+
+It focuses on:
+
+- Registering extra fields on multiple entities (Product, Category, Customer)
+- Covering multiple **scopes** (`common`, `lang`, `shop`) and **types** (bool, date, money, html, json, url, …)
+- Unregistering extra fields on uninstall (including dropping the SQL storage columns)
+- Rendering the stored values on the Front Office using hooks
+- Making Back Office translation strings visible in the translation interface
+
+## What it registers
+
+### Product (`product`)
+
+- `is_dangerous` (scope: `common`, type: bool)
+- `video_link` (scope: `lang`, type: string/url)
+- `custom_date` (scope: `shop`, type: date)
+
+### Category (`category`)
+
+- `theme_color` (scope: `common`, type: string/color)
+- `marketing_note` (scope: `common`, type: html)
+- `id_supplier` (scope: `common`, type: int / supplier selector)
+
+### Customer (`customer`)
+
+- `credit_limit` (scope: `common`, type: float / money)
+- `extra_json` (scope: `common`, type: json)
+
+## How to test
+
+This module impacts both Back Office and Front Office.
+
+### Product
+
+**Back Office grid**
+
+- Adds a **"Dangerous product"** field displayed after **"Quantity"**.
+- Adds a **"Custom date"** field displayed at the end of the grid.
+- Toggling **"Dangerous product"** persists the value.
+
+**Back Office form**
+
+- Extra fields are grouped into a dedicated **"Extra fields"** tab.
+- Except **"Dangerous product"**, which is displayed at the end of the **"Options"** tab.
+
+**Front Office hooks**
+
+- Product page: `displayProductAdditionalInfo`
+- Cart: `displayCartExtraProductInfo`
+
+### Category
+
+**Back Office grid**
+
+- Adds **Theme color** and **Marketing note** at the end of the grid.
+
+**Back Office form**
+
+- Adds **Theme color** and **Marketing note** to the form.
+
+**Front Office hooks**
+
+- Category listing page: `displayHeaderCategory`
+
+### Customer
+
+**Back Office grid**
+
+- Adds **Credit limit** in the grid.
+
+**Back Office form**
+
+- Adds **Credit limit** and **Metadata JSON** to the form.
+
+**Front Office hooks**
+
+- My account page: `displayCustomerAccountTop`
+
+### Where to find values in FO templates
+
+On the Front Office, the module displays **only the values stored for this module**, under `extraProperties['demoextrafield']`.
+
+## Translation note (Back Office)
+
+Each extra field has a **title** and a **description** meant to be displayed in Back Office.
+The system stores the source wording and its translation domain (for the default language), then translations are managed through PrestaShop Back Office.
+
+To make those strings appear in the Back Office translation interface, two conditions must be met:
+
+1. The strings must be declared in PHP via `$this->trans(...)` (see `demoextrafield::registerTranslationWordings()`).
+2. The same source strings must exist at least once in an XLF file shipped by the module (see `translations/fr-FR/ModulesDemoextrafieldAdmin.fr-FR.xlf`).
+
+## Supported PrestaShop versions
+
+Compatible with 9.2 ? and above versions.
+
+## How to install
+
+1. Download or clone the module into the `modules` directory of your PrestaShop installation
+2. Install the module:
+  - from Back Office in Module Manager
+  - or using the command `php ./bin/console prestashop:module install demoextrafield`
