# Language Management

> Translations, language switcher, content-language cookie, multi-line edits, root-level JSON, game and challenge language support

Nudj is built for multi-language out of the box. Every piece of content — challenges, rewards, achievements, posts, games, leaderboards, variables — supports translations.

## The translation editor

Community Settings -> Languages. The editor shows:

* Every translation key in the community.
* The English source string.
* Per-locale translations.
* Multi-line support (#589) for long copy blocks.
* Root-level JSON edits (#2012) for advanced use cases.

The editor loads English on open (#716) so you always see the baseline.

***

## Language switcher

The admin has an in-app language switcher (#746, #1053) — flip between locales to see how members in that language experience content.

Posts studio has a **dedicated sidebar language switcher** (#2226) for in-flow translation during content creation.

***

## Content-language cookie + API `x-language` header

Nudj sets a **content-language cookie** (#1916) that controls the `x-language` header on every API request. This makes the backend language-aware without URL prefixes. Adjust the cookie from the **content-language setting on the translations screen** (#1043).

***

## Multi-language variables

Question action variables (#1171) support translation — the prompt, options, and stored data can all be localised.

***

## Language key reference

A **language key reference** (#579) lists every key used in the community with its location. Helpful when you're translating and want to see where a string appears.

## Adding a new language

<Steps>
  <Step title="Enable the language" icon="circle-plus">
    Community Settings -> Languages -> Add. Pick the locale.
  </Step>

  <Step title="Import defaults" icon="download">
    New-language translations (#1163) ship with sensible platform defaults — so members see a usable app even before you translate every key.
  </Step>

  <Step title="Translate custom content" icon="pen">
    Per-challenge, per-reward, per-achievement translation. Language switch bugs across the admin were fixed in #845, #868, #2137, #2247.
  </Step>

  <Step title="Set default" icon="star">
    Optional: mark a non-English language as community default.
  </Step>
</Steps>

***

## Games support

Games ship with **French and German defaults** (#2011) built-in. Other languages use the standard translation flow.

  <Accordion title="Switching language breaks the form" icon="triangle-exclamation">
    Older bug, fixed across #845, #868, #2137, #2247. Hard-refresh. If it persists, clear the Turbopack cache.
  </Accordion>

  <Accordion title="Members see English in a non-English community" icon="earth-americas">
    Check the content-language cookie (#1916, #1043). It should match the community default.
