+### Design System translations
+
+We have [separate Lokalise project](https://app.lokalise.com/project/600119985e68c8ed361798.78610565) for translations used inside the Design System components. While editing keys there, keep in mind that they are shared between the apps and UI SDKs so make sure to consult it with the SDK team if it may effect them.
+
+To update strings for the `BabylonDesignLibrary` use the lane:
+```
+bundle exec fastlane lokalise_pull                // download all projects, including Design System
+bundle exec fastlane lokalise_pull_design_library // download only Design System project
+```
+
+### UI SDKs translations
+
+Similarly to Design System, we have [separate Lokalise project](https://app.lokalise.com/project/559388585e68a93fd45488.75156497) for translations used inside the UI SDKs. Translations in this project should be only modified by the SDK team.
+
+To update strings for the UI SDKs use the lane:
+```
+bundle exec fastlane lokalise_pull      // download all projects, including UI SDKs
+bundle exec fastlane lokalise_pull_sdks // download only SDK project
+```
