-This repo contains a very simple FUSE filesystem example in Python. It's the
-code from a post I wrote a while back:
+This repo contains a fuse-filesystem, which creates automagically a directory in users $HOME 
+and subdir in directory $HOME/archive/workdir with todays date as subdirname. 
+All directories are created, if not existent.
 
-https://www.stavros.io/posts/python-fuse-filesystem/
+It also contains a systemd-unit for users systemd-process, which will start on login and ends, when user logs out.
 
-If you see anything needing improvement or have any feedback, please open an
-issue.
+Run setup.sh, to install it for one user.
+
+Run setup-system.sh to install it for all users
