[Earlier I posted][1] about this same topic and wondered if Windows users would need to have a copy of [Frontier][2] running. The answer is no.
But Windows users who want to use the Markdown tool will need to have the `ScriptControlDLL.dll` and the `COMDll.dll` installed. At least until the new kernel is released.
If you’re a Windows user and you want to run the Markdown tool let me know. I can provide all the DLLs and the `Markdown.root`.
