- Python version 3.8+
- Node.js version 22+ (minimum `>=22.22.0` as specified in `package.json`)
- pnpm version 11+ (`corepack enable pnpm`)
- Python version 3.12+ (matching backend `apps/api/Dockerfile.api`)

`setup.sh` automatically copies the required `.env` files, generates the Django `SECRET_KEY`, enables `pnpm` via Corepack, and installs dependencies (`pnpm install`).

> **Manual alternative**: If configuring environment files manually without `setup.sh`, ensure you install frontend dependencies by running `pnpm install` before starting services.

#### File organization

Translations are organized by language in the locales directory. Each language has its own folder containing JSON files for translations. Here's how it looks:
Translations are organized by language in the `packages/i18n/src/locales/` directory. Each language has its own folder containing modular JSON files corresponding to feature namespaces (defined in `NAMESPACES` in `packages/i18n/src/constants/namespaces.ts`). Here's how it looks:

Add a language tag to the directory-tree code fence.

The fence at Line 123 has no language tag. markdownlint reports MD040 for this block. Mark it as text so the guide passes the Markdown lint rule.

#### Nested structure

To keep translations organized, we use a nested structure for keys. This makes it easier to manage and locate specific translations. For example:

#### Updating existing translations

1. Locate the key in `locales/<language>/translations.json`.

1. Identify the relevant namespace (e.g., `common`, `auth`, `project`, `work-item`) and locate the file in `packages/i18n/src/locales/<language>/<namespace>.json`.
2. Update the value while ensuring the key structure remains intact.
3. Preserve any existing ICU formats (e.g., variables, pluralization).

#### Adding new translation keys

1. When introducing a new key, ensure it is added to **all** language files, even if translations are not immediately available. Use English as a placeholder if needed.

1. When introducing a new key, determine its namespace and add it to the corresponding namespace file across **all** language directories. Use English (`en/<namespace>.json`) as the source of truth and reference placeholder.
2. Keep the nesting structure consistent across all languages.

3. If the new key requires dynamic content (e.g., variables or pluralization), ensure the ICU format is applied uniformly across all languages.

### Adding new languages

Adding a new language involves several steps to ensure it integrates seamlessly with the project. Follow these instructions carefully:
Adding a new language involves three straightforward steps:

1. **Update type definitions**
Add the new language to the TLanguage type in the language definitions file:
1. **Update type definitions**
Add the new language code (e.g., `your-lang`) to the `TLanguage` type union:

```ts
// packages/i18n/src/types/language.ts
export type TLanguage = "en" | "fr" | "your-lang";
```
```ts
// packages/i18n/src/types/language.ts
export type TLanguage = "en" | "fr" | "your-lang" | ...;

Keep the TLanguage example valid TypeScript.

Remove | ... from the union. The example should end with "your-lang";.

1. **Add language configuration**
Include the new language in the list of supported languages:
2. **Add language configuration**
Include the new language option in the `SUPPORTED_LANGUAGES` list:

```ts
// packages/i18n/src/constants/language.ts
export const SUPPORTED_LANGUAGES: ILanguageOption[] = [
{ label: "English", value: "en" },
{ label: "Your Language", value: "your-lang" },
];
```

2. **Create translation files**
1. Create a new folder for your language under locales (e.g., `locales/your-lang/`).

2. Add a `translations.json` file inside the folder.
```ts
// packages/i18n/src/constants/language.ts
export const SUPPORTED_LANGUAGES: ILanguageOption[] = [
{ label: "English", value: "en" },
{ label: "Your Language", value: "your-lang" },
];
```

3. Copy the structure from an existing translation file and translate all keys.
3. **Create translation files**
1. Create a new folder for your language under locales (e.g., `packages/i18n/src/locales/your-lang/`).
2. Copy the namespace JSON files from `packages/i18n/src/locales/en/` into your new folder.
3. Translate the keys across the namespace files.

3. **Update import logic**
Modify the language import logic to include your new language:

```ts
private importLanguageFile(language: TLanguage): Promise<any> {
switch (language) {
case "your-lang":
return import("../locales/your-lang/translations.json");
// ...
}
}
```
> **Note**: Translations are dynamically imported at runtime via `i18next-resources-to-backend` in `packages/i18n/src/core/instance.ts`. No manual loader functions or code edits to import statements are needed.
