I stumbled upon this great little markdown visualizer tool created by Joshua Wuyts called VMD. For those using a lot of markdown in the commandline it can be extremely useful to quickly view a compiled version of your markdown file in pretty github style formatting.
Because the tool is written in nodejs and electron you can install it globally using
npm install -g vmd
and use it on any markdown file using
VMD then instantly shows a window with a rendered version of your markdown file. It even watches the original file for changes and instantly updates the rendered version if you save the file!
