Galley - A beautiful, free Markdown reader. Set it as your default.

Hey, I made a free Markdown reader for the Mac. Double-click a .md file and it just renders nicely instead of showing raw text or opening in your code editor. It's read-only by default (there's a quick edit mode if you need to fix something), has five themes, and renders Mermaid diagrams and math. I built it because I wanted something simple to set as my default .md viewer and nothing quite fit. It's free, open source, and doesn't track anything. Would love for you to try it and let me know what you think.
