English as the source language for the project cannot be added to Crowdin anymore.
If you need to modify the source language content, it is recommended to submit a pull request for the changes.

• major: core/resources/src/main/res/values/strings.xml
• languages: core/resources/src/main/res/values/languages.xml
• android next: eggs/AndroidNext/src/main/res/values/strings.xml
