+### Weblate
+
+I have chosen to use Weblate as a platform for translations.
+Weblate provides an easy-to-use web-based interface that allows translators to collaborate and work on translations.
+
+To get started with translating the app on Weblate, simply [visit the translation page](https://hosted.weblate.org/engage/nextcloud-cookbook/) and select your preferred language.
+You can then start translating the app directly on the platform.
+
+There are two components: [App](https://hosted.weblate.org/projects/nextcloud-cookbook/app/) and [Fastlane](https://hosted.weblate.org/projects/nextcloud-cookbook/fastlane/).
+
+Fastlane is a collection of app store metadata that is used to submit the app to F-Droid and Play Store.
+
+App contains all strings used in the app.
+
+### XML
 
 Please fork the repository, make your changes to the XML files and submit a pull request. Remember
 to include information about what language it is.
