What program opens a .md file?

Adobe Reader, Preview, any browser, LibreOffice, Word. Or drop it here, without installing anything.

Why won't my .md open?

Either the viewer does not know Markdown (plain text with light formatting. the native language of readme files and note apps.), or the file is damaged or misnamed. Converting to PDF fixes the first case.

Is it safe to open a .md here?

Yes: the file is read in your browser and never leaves your device.
