Open MD file in terminal

Could I open markdown file in terminal?

I’ve tried to do this:
/Applications/Panda.app/Contents/MacOS/Panda ./README.md

But catch error The document “README.md” could not be opened. The file doesn’t exist.. The file is exists.

If I’ve try /Applications/Panda.app/Contents/MacOS/Panda pwd/README.md, catch error: The document “README.md” could not be opened. You don’t have permission.

Something like this works via others editors like Sublime, VSCode etc.

I think it will improve user experience.
