 If the argument is a file path, VFS uses the ''vfs_lookup_internal()'' function to
 translate the path into the so called VFS triplet. A VFS triplet is an ordered
 triplet containing a global handle of the file system instance, a global device
 handle and a file index. Thus a VFS triplet uniquely identifies a file on
-some file system instance.
+some file system instance. An example VFS triplet looks like this:
 
+{{{
+        (2, 1, 10)
+}}}
+
+In the above example, the VFS triplet describes a file on a file system which was
+assigned number 2 by the VFS service, located on a device, which was assigned number
+1 by the DEVMAP service, and which has a file-system dependent index number 10. The
+last number is also known as i-node number in other operating systems.
+
+VFS keeps information about each referenced file in an abstraction called VFS
+node, for which there is the ''vfs_node_t'' type. Thus, a VFS node represents
+some file which is referenced by VFS.
