Help us make K-9 Mail even better!
K9 Mail uses Transifex for translations. As features are added, there is often a need for translators to localise the text accordingly.
Help other users by answering questions on the mailing list.
The source code is hosted on GitHub.
If you are new to Android then the Android Developer site has lots of helpful resources.
A number of the issues are marked with the ‘beginner’ label indicating they are probably suitable for someone with not much experience of K-9.
The design of K-9 is constantly evolving. We have recently started to work on formalising our design guidelines for the app in a design repository.
Like everything else, this manual is the work of volunteers. If you feel it could be improved with information on a certain topic, feel free to contribute by creating an issue on the website’s tracker or submitting a pull request.
