+A kiwi-scp instance is a directory containing a bunch of static configuration files.
 "Static" there as in "those don't change during normal service operation".
 These files  could be anything from actual `.conf` files to entire html-web-roots.
 
 Non-static, but persistent files are to be kept in a "service data directory", by default `/var/kiwi`.
 In your `docker-compose.yml` files, you can refer to that directory as **${TARGETROOT}**.
