Simply run a web server from the command line that will render your markdown files as html live.
pip install markdown-live should work. It's compatible with python 2.7, and python 3.4+.
Installing markdown-live will install the markdown_live executable, which can be used as such:
usage: markdown_live [-h] [-p PORT] [-v] [LOCATION]
Render markdown files and serve them with an http server.
optional arguments:
-h, --help show this help message and exit
-p PORT, --port PORT Serve on this port instead of the default (port 8000)
-v, --version Just print out the version number
LOCATION either a markdown file to just render that
file, or a directory to server files from that
directory
The package is currenly available on pypi here.
