 ## Translations
 
-* [Translations are managed in the Transiflex Project of the iD Editor](https://www.transifex.com/openstreetmap/id-editor/translate/#en_GB/presets/84278008).
 * English translations for the `terms`-key should be added to the JSON data ([Exampple](https://github.com/openstreetmap/id-tagging-schema/blob/main/data/presets/natural/shrub.json#L16-L19)).
 
+* Apart from that, translations are managed [in the Transifex Project of the iD Editor](https://www.transifex.com/openstreetmap/id-editor/) inside the translation resource _'preset'_. 
+
+  To change translation, you can [open the translation page](https://www.transifex.com/openstreetmap/id-editor/translate/), select a language, select _'preset'_ and search for `key:living_street` or `translation_text:'Living Street'` to find and change translations.
