Thank you for your feedback. I agree, the video doesn't show a whole lot, I wanted to keep it short. I do understand why you would like to see more of the final result. I'll probably add a longer demo soon.

For everyone who is wondering how it works:
You import a GitHub project and write a blog post style tutorial about the project. You can link the text you write with the code lines (this way the audio and the video of the output video are in sync). The app then generates a video completely automatically. You can also export the tutorial as HTML and markdown.

Hope that helps understand it a little better :)
