Its a platform for creating tutorials/stories only using Markdown.

You can - Create step-wise tutorials

- Embed YouTube videos on your posts

- Add all your posts to your personal website with just one line of code

- Measure how your posts perform over time with views/likes/location metrics

- Suggest improvements for a tutorial similar to a pull request in Github (still in active development, will be released by this weekend :) )

- Add projects and show it to the community so that you can find a partner to work on your project.
