Agama is an open source project and as such it welcomes all kinds of contributions. But this is a special helper repository not intended for direct contributions.
For adding or updating the translations it is recommended to use the Weblate online tool. Weblate provides a nice web interface and the changes are automatically saved to this repository.
If you find a bug in original untranslated text then please open an issue in the main Agama GitHub repository.
Thank you in advance for your help!
