 ⚠️ For some advanced features (ex: Export as PDF) Docs relies on XL packages from BlockNote. These are licenced under AGPL-3.0 and are not MIT compatible. You can perfectly use Docs without these packages by setting the environment variable `PUBLISH_AS_MIT` to true. That way you'll build an image of the application without the features that are not MIT compatible. Read the [environment variables documentation](/docs/env.md) for more information.

+# Customization Guide 🛠  ️
+
+## Runtime Theming 🎨
+
+### How to Use
+
+To use this feature, simply set the `FRONTEND_CSS_URL` environment variable to the URL of your custom CSS file. For example:
+
+```javascript
+FRONTEND_CSS_URL=http://anything/custom-style.css
+```
+
+Once you've set this variable, Docs will load your custom CSS file and apply the styles to our frontend application.
+
+### Benefits
+
+This feature provides several benefits, including:
+
+*   **Easy customization** 🔄: With this feature, you can easily customize the look and feel of our application without requiring any code changes.
+*   **Flexibility** 🌈: You can use any CSS styles you like to create a custom theme that meets your needs.
+*   **Runtime theming** ⏱️: This feature allows you to change the theme of our application at runtime, without requiring a restart or recompilation.
+
+### Example Use Case
+
+Let's say you want to change the background color of our application to a custom color. You can create a custom CSS file with the following contents:
+
+```css
+body {
+  background-color: #3498db;
+}
+```
+
+Then, set the `FRONTEND_CSS_URL` environment variable to the URL of your custom CSS file. Once you've done this, our application will load your custom CSS file and apply the styles, changing the background color to the custom color you specified.
+
+----
+
+## Runtime JavaScript Injection 🚀
+
+### How to Use
+
+To use this feature, simply set the `FRONTEND_JS_URL` environment variable to the URL of your custom JavaScript file. For example:
+
+```javascript
+FRONTEND_JS_URL=http://anything/custom-script.js
+```
+
+Once you've set this variable, Docs will load your custom JavaScript file and execute it in the browser, allowing you to modify the application's behavior at runtime.
+
+### Benefits
+
+This feature provides several benefits, including:
+
+*   **Dynamic customization** 🔄: With this feature, you can dynamically modify the behavior and appearance of our application without requiring any code changes.
+*   **Flexibility** 🌈: You can add custom functionality, modify existing features, or integrate third-party services.
+*   **Runtime injection** ⏱️: This feature allows you to inject JavaScript into the application at runtime, without requiring a restart or recompilation.
+
+### Example Use Case
+
+Let's say you want to add a custom menu to the application header. You can create a custom JavaScript file with the following contents:
+
+```javascript
+(function() {
+  'use strict';
+
+  function initCustomMenu() {
+    // Wait for the page to be fully loaded
+    const header = document.querySelector('header');
+    if (!header) return false;
+
+    // Create and inject your custom menu
+    const customMenu = document.createElement('div');
+    customMenu.innerHTML = '<button>Custom Menu</button>';
+    header.appendChild(customMenu);
+    
+    console.log('Custom menu added successfully');
+    return true;
+  }
+
+  // Initialize when DOM is ready
+  if (document.readyState === 'loading') {
+    document.addEventListener('DOMContentLoaded', initCustomMenu);
+  } else {
+    initCustomMenu();
+  }
+})();
+```
+
+Then, set the `FRONTEND_JS_URL` environment variable to the URL of your custom JavaScript file. Once you've done this, our application will load your custom JavaScript file and execute it, adding your custom menu to the header.
+
+----
+
+## **Your Docs icon** 📝
+
+You can add your own Docs icon in the header from the theme customization file.
+
+### Settings 🔧
+
+```shellscript
+THEME_CUSTOMIZATION_FILE_PATH=<path>
+```
+
+### Example of JSON
+
+You can activate it with the `header.icon` configuration: https://github.com/suitenumerique/docs/blob/main/src/helm/env.d/dev/configuration/theme/demo.json
+
+This configuration is optional. If not set, the default icon will be used.
+
+----
+
+## **Footer Configuration** 📝
+
+The footer is configurable from the theme customization file.
+
+### Settings 🔧
+
+```shellscript
+THEME_CUSTOMIZATION_FILE_PATH=<path>
+```
+
+### Example of JSON
+
+The json must follow some rules: https://github.com/suitenumerique/docs/blob/main/src/helm/env.d/dev/configuration/theme/demo.json
+
+`footer.default` is the fallback if the language is not supported.
+
+--- 
+Below is a visual example of a configured footer ⬇️:
+
+![Footer Configuration Example](./assets/footer-configurable.png)
+
+----
+
+## **Custom Translations** 📝
+
+The translations can be partially overridden from the theme customization file.
+
+### Settings 🔧
+
+```shellscript
+THEME_CUSTOMIZATION_FILE_PATH=<path>
+```
+
+### Example of JSON
+
+The json must follow some rules: https://github.com/suitenumerique/docs/blob/main/src/helm/env.d/dev/configuration/theme/demo.json
+
+----
+
+## **Waffle Configuration** 🧇
+
+The Waffle (La Gaufre) is a widget that displays a grid of services.
+
+![Waffle Configuration Example](./assets/waffle.png)
+
+### Settings 🔧
+
+```shellscript
+THEME_CUSTOMIZATION_FILE_PATH=<path>
+```
+
+### Configuration
+
+The Waffle can be configured in the theme customization file with the `waffle` key.
+
+### Available Properties
+
+See: [LaGaufreV2Props](https://github.com/suitenumerique/ui-kit/blob/main/src/components/la-gaufre/LaGaufreV2.tsx#L49)
+
+### Complete Example
+
+From the theme customization file: https://github.com/suitenumerique/docs/blob/main/src/helm/env.d/dev/configuration/theme/demo.json
+
+### Behavior
+
+- If `data.services` is provided, the Waffle will display those services statically
+- If no data is provided, services can be fetched dynamically from an API endpoint thanks to the `apiUrl` property

 Please remember that `*.127.0.0.1.nip.io` will always resolve to `127.0.0.1`, except in the k8s cluster where we configure CoreDNS to answer with the ingress-nginx service IP.
 
+The namespace `impress` is already created, you can work in it and configure your kubectl cli to use it by default.
+
+```
+$ kubectl config set-context --current --namespace=impress
+```
+
 ## Preparation
 
+We provide our own helm chart for all development dependencies, it is available here https://github.com/suitenumerique/helm-dev-backend
+This provided chart is for development purpose only and is not ready to use in production.
+
+You can install it on your cluster to deploy keycloak, minio, postgresql and redis.
+
 ### What do you use to authenticate your users?
 
 Docs uses OIDC, so if you already have an OIDC provider, obtain the necessary information to use it. In the next step, we will see how to configure Django (and thus Docs) to use it. If you do not have a provider, we will show you how to deploy a local Keycloak instance (this is not a production deployment, just a demo).

+# Language Configuration (2025-12)
+
+This document explains how to configure and override the available languages in the Docs application.
+
+## Default Languages
+
+By default, the application supports the following languages (in priority order):
+
+- English (en-us)
+- French (fr-fr)
+- German (de-de)
+- Dutch (nl-nl)
+- Spanish (es-es)
+
+The default configuration is defined in `src/backend/impress/settings.py`:
+
+```python
+LANGUAGES = values.SingleNestedTupleValue(
+    (
+        ("en-us", "English"),
+        ("fr-fr", "Français"),
+        ("de-de", "Deutsch"),
+        ("nl-nl", "Nederlands"),
+        ("es-es", "Español"),
+    )
+)
+```
+
+## Overriding Languages
+
+### Using Environment Variables
+
+You can override the available languages by setting the `DJANGO_LANGUAGES` environment variable. This is the recommended approach for customizing language support without modifying the source code.
+
+#### Format
+
+The `DJANGO_LANGUAGES` variable expects a semicolon-separated list of language configurations, where each language is defined as `code,Display Name`:
+
+```
+DJANGO_LANGUAGES=code1,Name1;code2,Name2;code3,Name3
+```
+
+#### Example Configurations
+
+**Example 1: English and French only**
+
+```bash
+DJANGO_LANGUAGES=en-us,English;fr-fr,Français
+```
+
+**Example 2: Add Italian and Chinese**
+
+```bash
+DJANGO_LANGUAGES=en-us,English;fr-fr,Français;de-de,Deutsch;it-it,Italiano;zh-cn,中文
+```
+
+**Example 3: Custom subset of languages**
+
+```bash
+DJANGO_LANGUAGES=fr-fr,Français;de-de,Deutsch;es-es,Español
+```
+
+### Configuration Files
+
+#### Development Environment
+
+For local development, you can set the `DJANGO_LANGUAGES` variable in your environment configuration file:
+
+**File:** `env.d/development/common.local`
+
+```bash
+DJANGO_LANGUAGES=en-us,English;fr-fr,Français;de-de,Deutsch;it-it,Italiano;zh-cn,中文;
+```
+
+#### Production Environment
+
+For production deployments, add the variable to your production environment configuration:
+
+**File:** `env.d/production.dist/common`
+
+```bash
+DJANGO_LANGUAGES=en-us,English;fr-fr,Français
+```
+
+#### Docker Compose
+
+When using Docker Compose, you can set the environment variable in your `compose.yml` or `compose.override.yml` file:
+
+```yaml
+services:
+  app:
+    environment:
+      - DJANGO_LANGUAGES=en-us,English;fr-fr,Français;de-de,Deutsch
+```
+
+## Important Considerations
+
+### Language Codes
+
+- Use standard language codes (ISO 639-1 with optional region codes)
+- Format: `language-region` (e.g., `en-us`, `fr-fr`, `de-de`)
+- Use lowercase for language codes and region identifiers
+
+### Priority Order
+
+Languages are listed in priority order. The first language in the list is used as the fallback language throughout the application when a specific translation is not available.
+
+### Translation Availability
+
+Before adding a new language, ensure that:
+
+1. Translation files exist for that language in the `src/backend/locale/` directory
+2. The frontend application has corresponding translation files
+3. All required messages have been translated
+
+#### Available Languages
+
+The following languages have translation files available in `src/backend/locale/`:
+
+- `br_FR` - Breton (France)
+- `cn_CN` - Chinese (China) - *Note: Use `zh-cn` in DJANGO_LANGUAGES*
+- `de_DE` - German (Germany) - Use `de-de`
+- `en_US` - English (United States) - Use `en-us`
+- `es_ES` - Spanish (Spain) - Use `es-es`
+- `fr_FR` - French (France) - Use `fr-fr`
+- `it_IT` - Italian (Italy) - Use `it-it`
+- `nl_NL` - Dutch (Netherlands) - Use `nl-nl`
+- `pt_PT` - Portuguese (Portugal) - Use `pt-pt`
+- `ru_RU` - Russian (Russia) - Use `ru-ru`
+- `sl_SI` - Slovenian (Slovenia) - Use `sl-si`
+- `sv_SE` - Swedish (Sweden) - Use `sv-se`
+- `tr_TR` - Turkish (Turkey) - Use `tr-tr`
+- `uk_UA` - Ukrainian (Ukraine) - Use `uk-ua`
+- `zh_CN` - Chinese (China) - Use `zh-cn`
+
+**Note:** When configuring `DJANGO_LANGUAGES`, use lowercase with hyphens (e.g., `pt-pt`, `ru-ru`) rather than the directory name format.
+
+### Translation Management
+
+We use [Crowdin](https://crowdin.com/) to manage translations for the Docs application. Crowdin allows our community to contribute translations and helps maintain consistency across all supported languages.
+
+**Want to add a new language or improve existing translations?**
+
+If you would like us to support a new language or want to contribute to translations, please get in touch with the project maintainers. We can add new languages to our Crowdin project and coordinate translation efforts with the community.
+
+### Cookie and Session
+
+The application stores the user's language preference in a cookie named `docs_language`. The cookie path is set to `/` by default.
+
+## Testing Language Configuration
+
+After changing the language configuration:
+
+1. Restart the application services
+2. Verify the language selector displays the correct languages
+3. Test switching between different languages
+4. Confirm that content is displayed in the selected language
+
+## Troubleshooting
+
+### Languages not appearing
+
+- Verify the environment variable is correctly formatted (semicolon-separated, comma between code and name)
+- Check that there are no trailing spaces in language codes or names
+- Ensure the application was restarted after changing the configuration
+
+### Missing translations
+
+If you add a new language but see untranslated text:
+
+1. Check if translation files exist in `src/backend/locale/<language_code>/LC_MESSAGES/`
+2. Run Django's `makemessages` and `compilemessages` commands to generate/update translations
+3. Verify frontend translation files are available
+
+## Related Configuration
+
+- `LANGUAGE_CODE`: Default language code (default: `en-us`)
+- `LANGUAGE_COOKIE_NAME`: Cookie name for storing user language preference (default: `docs_language`)
+- `LANGUAGE_COOKIE_PATH`: Cookie path (default: `/`)

+# User account reconciliation
+
+It is possible to merge user accounts based on their email addresses.
+
+Docs does not have an internal process to requests, but it allows the import of a CSV from an external form
+(e.g. made with Grist) in the Django admin panel (in "Core" > "User reconciliation CSV imports" > "Add user reconciliation")
+
+## CSV file format
+
+The CSV must contain the following mandatory columns:
+
+- `active_email`: the email of the user that will remain active after the process.
+- `inactive_email`: the email of the user(s) that will be merged into the active user. It is possible to indicate several emails, so the user only has to make one request even if they have more than two accounts.
+- `id`: a unique row id, so that entries already processed in a previous import are ignored.
+
+The following columns are optional: `active_email_checked` and `inactive_email_checked` (both must contain `0` (False) or `1` (True), and both default to False.)
+If present, it allows to indicate that the source form has a way to validate that the user making the request actually controls the email addresses, skipping the need to send confirmation emails (cf. below)
+
+Once the CSV file is processed, this will create entries in "Core" > "User reconciliations" and send verification emails to validate that the user making the request actually controls the email addresses (unless `active_email_checked` and `inactive_email_checked` were set to `1` in the CSV)
+
+In "Core" > "User reconciliations", an admin can then select all rows they wish to process and check the action "Process selected user reconciliations". Only rows that have the status `ready` and for which both emails have been validated will be processed.
+
+## Settings
+
+If there is a problem with the reconciliation attempt (e.g., one of the addresses given by the user does not match an existing account), the email signaling the error can give back the link to the reconciliation form. This is configured through the following environment variable:
+
+```env
+USER_RECONCILIATION_FORM_URL=<url used in the email for reconciliation with errors to allow a new requests>
+# e.g. "https://yourgristinstance.tld/xxxx/UserReconciliationForm"
+```
