Most of the time you can use jemdoc without any additional flags. For example, typing jemdoc index.jemdoc will produce an index.html, using a default configuration. You can change the output file by using -o OUTFILE, for example jemdoc -o html/main.html index.jemdoc Some configuration options can be overridden by specifying a configuration file. You can use jemdoc --show-config to print a sample configuration file (which includes all of the default options). Any or all of the configuration [blocks] can be overwritten by including them in a configuration file, and running, for example, jemdoc -c mywebsite.conf index.jemdoc See http://jemdoc.jaboc.net/ for more details.
