Document Archive
CLICK HERE FOR DEMO
The demo shows a way to create and organize documents using a simple flat-file data storage system. Document text is entered in markdown format, then converted to html. Both versions are saved in a text file 'records'.
Previous versions are saved after each edit and can be accessed if needed. Documents can be assigned to categories as well.
