I mainly use trillium and want to import my notes. Unsure how to do it without windows. Even with windows the instructions seem unclear

Edit: Here’s what I did: I got my partner’s windows computer and put my onenote notebook on it via file transfer. Then I made folders for every notebook and subnotebook. Finally I would through each section and exported it as a docx. Then I found an app on fedora that can convert docx to anything, and I chose markdown. Then imported these into Trilium. I could have exported each note but that would have taken 10x as long and the section export feature makes clear new notes.

Final comment: importing markdown into Trilium took one second. For formatting sake, I tried to import html as well and it crash the app.
