Hi @seankim641
Have you tried just exporting your knowledge base as markdown (see screenshot) and opening the unzipped folder in Obsidian?
I just tried it, It mostly works except for some backlinks and the spaced repetition cards of course. I think some issues could be fixed with Regex search-and-replace.
PS: I think that the github script does not work anymore with the current version of RemNote as it was last updated in October 2021.
