Great tool, but I can't figure out how to link to a file for download. I have several csv files and PDFs in \docs\downloads linked with `[filename](./downloads/filename.pdf)`. Gets 404 error, and path includes the `./` I'm porting over from Slate, and this is the last major hurdle. <!-- Love docsify?
