[remark](https://github.com/remarkjs/remark) plugin to transform remark syntax tree ([mdast](https://github.com/syntax-tree/mdast)) to [Slate](https://github.com/ianstormtaylor/slate) document tree, and vice versa. Made for WYSIWYG markdown editor.

[remark](https://github.com/remarkjs/remark) is popular markdown parser/serializer which data structure can be converted to what used in [rehype](https://github.com/rehypejs/rehype), [retext](https://github.com/retextjs/retext) and so on. [Slate](https://github.com/ianstormtaylor/slate) is fully customizable rich text editor built on [React](https://github.com/facebook/react). Connect both 2 worlds should be great...
