+## Interface text and translations
+
+StepForge's interface is in English, French, Spanish, Russian, Simplified
+Chinese and Japanese. `core/i18n.js` explains how it works. In short:
+
+- Write interface text in English, inside `t('…')`, and put values in
+  placeholders: `t('Move to {folder}', { folder: name })`. Text that changes
+  with a number uses `tn(count, '{count} step', '{count} steps')`. The main
+  process uses `t` for its own dialogs.
+- Keep each message one whole sentence in one string literal. Don't join
+  fragments or build text at run time: word order differs between languages,
+  and `npm run translations` can only find literals.
+- `npm run translations` lists the text each language in `core/locales/` is
+  missing. Missing text shows in English, so the app still works, but add the
+  translations before a release. Plural entries give one string per plural
+  category of the language (`one`/`other`, and `few`/`many` for Russian).
+- Product names (StepForge, GitHub, Confluence, Wiki.js, Ollama), key names
+  and file extensions stay as they are. Exported guides are English only.
+
+To add a language, add it to `LANGUAGES` in `core/i18n.js`, add its catalog
+to `core/locales/` and `core/locales/index.js`, and load it with a script tag
+in `app/renderer/index.html`. The Microsoft Store package lists every language
+in `LANGUAGES` (see `docs/windows/MICROSOFT_STORE_RELEASE.md`).
