Contribute
This app is an open project and thrives on contributions. You don't have to be a pro — even pointing out a mistake or an unclear wording helps.
Comment right on the page
The quickest way to give feedback is right here in the app: highlight a passage, add your comment, and send all your feedback at the end together as a file or email. Nothing is stored — your notes stay in this session only.
Report mistakes or suggest improvements
Spotted a factual error, a typo or a confusing explanation? Have an idea for how a module could be better? Report it via the Issues on GitHub — short and informal is fine.
Help with translation
The app is built for multiple languages. If you're fluent in one of the target languages, you can help translate and review the content.
Contribute code
Enjoy coding? Improvements to the app itself are welcome. Fork the project, make your change and send a pull request on GitHub.
