 ## Features
 
-Although there are already a number of Rmd to Jupyter converters such as [notedown](https://github.com/aaren/notedown), [RMD-to-Jupyter](https://github.com/lecy/RMD-to-Jupyter) (uses rpy2), they lack support for some of the Rmakdown features due to limitations of the Jupyter notebook platform. Fortunately, SoS Notebook, especially its Jupyter Lab extension addresses most of the limitations and offers an almost perfect conversion from R markdown to Jupyter notebook.

This is differnt from Rmarkdown's multi-language approach and might lead to different results. For example, whereas multiple Python3 cells are always executed by the same Python kernel, RMarkdown's Python code blocks can be executed independently (if without `reticulate`).
