 ## Internationalization (i18n)
 
-This project supports internationalization. Currently, only English language is supported. Pull requests to support additional languages are encouraged.

+
+Dependency-Track tries to detect the language preference from the user's browser.
+If no matching language is available, it will fall back to English.
+
+Users can customize their language preference via the profile dropdown menu:

+### Adding or Improving Translations
+
+Translations are defined in `src/i18n/locales/{lang}.json`, for example [en.json](src/i18n/locales/en.json).
+We recommend using [VS Code] with the [i18n Ally] extension when working on translation.
+The extension provides an overview of translation progress across all languages:
+
+![Translation progress in i18n Ally](.github/images/i18n_i18n-ally-progress.png)
+
+In case of missing translations, it is possible to translate automatically using Google Translate.
+To do this, hover over the _No Translation_ item of a language, and click the globe icon:
