Zettelstore is not just a service that provides services of a zettelkasten.
It allows some tasks to be executed at the command line.
Typically, the task (“sub-command”) will be given at the command line as the first parameter.

If no parameter is given, the Zettelstore is called as

    zettelstore

This is equivalent to calling it this way:

    mkdir -p ./zettel
    zettelstore run -d ./zettel -c ./.zscfg

Typically this is done by starting Zettelstore via a graphical user interface by double-clicking its file icon.
