+Samples for the VFS are mainly supplied in ``samples/subsys/fs``, although various examples of the
+VFS usage are provided as important functionalities in samples for different subsystems.
+Here is the list of samples worth looking at:
+
+- ``samples/subsys/fs/fat_fs`` is an example of FAT file system usage with SDHC media;
+- ``samples/subsys/shell/fs`` is an example of Shell fs subsystem, using internal flash partition
+	formatted to LittleFS;
