-For now strings are coming from Element Android project, so:
-- If you want to fix an issue with an English string, please submit a PR on Element Android.
-- If you want to fix an issue in other languages, or add a missing translation, or even add a new language, please use [Weblate](https://translate.element.io/projects/element-android/).
+The strings of the project are managed externally using [https://localazy.com](https://localazy.com) and shared with ElementX iOS.
+
+### I want to add new strings to the project
+
+Only the core team can modify or add English strings to Localazy. As an external contributor, if you want to add new strings, feel free to add an Android resource file to the project (for instance a file named `temporary.xml`), with a note in the description of the PR for the reviewer to integrate the String into `Localazy`. If accepted, the reviewer will add the String(s) for you, and then you can download them on your branch (following these [instructions](./tools/localazy/README.md#download-translations)) and remove the temporary file.
+
+Please follow the naming rules for the key. More details in [the dedicated section in this README.md](./tools/localazy/README.md#key-naming-rules)

 ### Accessibility
 
 Please consider accessibility as an important point. As a minimum requirement, in layout XML files please use attributes such as `android:contentDescription` and `android:importantForAccessibility`, and test with a screen reader if it's working well. You can add new string resources, dedicated to accessibility, in this case, please prefix theirs id with `a11y_`.
