> MyST is a flavor of markdown that is designed for simplicity, flexibility, and extensibility. This repository serves as the reference implementation of MyST Markdown, as well as a collection of tools to support working with MyST in Python and Sphinx. It contains an extended CommonMark-compliant parser using markdown-it-py, as well as a Sphinx extension that allows you to write MyST Markdown in Sphinx.

This project is just the first step towards making Spyder an educational tool. In the future, we hope that we can develop the infrastructure necessary to support in-IDE tutorials, by improving the tools like Jupyter Book, sphinx-thebe, MyST-Parser which will provide better integration to write educational tutorials.
