+## Organization modes
+
+Next organization modes supported:
+    
+- **copy** — copy files to target root. Make COW (using syscall) if FS supports it.
+- **hardlink** — create hardlink to the source file instead of copying. 
+The best choice if source and target are in same partition for compatibility
+and resource usage, but we can't chmod target files, because of original file mode will 
+be changed too. 
+- **move** — moves original files to new place.
+- **symlink** — create a symlink at the target for the source files.
