Quick instructions on installing MultiMarkdown.
aptitude install git tidy git clone https://github.com/fletcher/MultiMarkdown-4.git cd MultiMarkdown-4/ git submodule init git submodule update make install
Download and run the MultiMarkdown-Windows.exe file from https://fletcherpenney.net/multimarkdown/download/. Since Windows has a shit command line interface, your best bet for converting files from mmd to html is to create a shortcut icon that will convert any files dragged and dropped onto it. Do so with these instructions, lifted straight from the MMD site:
enter "multimarkdown" as the location of the item
choose the desired name for the shortcut
right-click on the new shortcut and select "Properties"
you can then add any desired command-line options at the end of the "Target" property field, after the last quotation mark. You should definitely include
-bto enable batch mode. The others are up to you.
The resulting html file(s) will appear in the same directory as the file(s) you dragged and dropped.
