+Introduction
+============
+
+  This is the client VFS module for the SMB3 NAS protocol as well
+  as for older dialects such as the Common Internet File System (CIFS)
+  protocol which was the successor to the Server Message Block
+  (SMB) protocol, the native file sharing mechanism for most early
+  PC operating systems. New and improved versions of CIFS are now
+  called SMB2 and SMB3. Use of SMB3 (and later, including SMB3.1.1
+  the most current dialect) is strongly preferred over using older
+  dialects like CIFS due to security reasons. All modern dialects,
+  including the most recent, SMB3.1.1, are supported by the CIFS VFS
+  module. The SMB3 protocol is implemented and supported by all major
+  file servers such as Windows (including Windows 2019 Server), as
+  well as by Samba (which provides excellent CIFS/SMB2/SMB3 server
+  support and tools for Linux and many other operating systems).
+  Apple systems also support SMB3 well, as do most Network Attached
+  Storage vendors, so this network filesystem client can mount to a
+  wide variety of systems. It also supports mounting to the cloud
+  (for example Microsoft Azure), including the necessary security
+  features.
+
+  The intent of this module is to provide the most advanced network
+  file system function for SMB3 compliant servers, including advanced
+  security features, excellent parallelized high performance i/o, better
+  POSIX compliance, secure per-user session establishment, encryption,
+  high performance safe distributed caching (leases/oplocks), optional packet
+  signing, large files, Unicode support and other internationalization
+  improvements. Since both Samba server and this filesystem client support the
+  CIFS Unix extensions, and the Linux client also suppors SMB3 POSIX extensions,
+  the combination can provide a reasonable alternative to other network and
+  cluster file systems for fileserving in some Linux to Linux environments,
+  not just in Linux to Windows (or Linux to Mac) environments.
+
+  This filesystem has a mount utility (mount.cifs) and various user space
+  tools (including smbinfo and setcifsacl) that can be obtained from
+
+      https://git.samba.org/?p=cifs-utils.git
+
+  or
+
+      git://git.samba.org/cifs-utils.git
+
+  mount.cifs should be installed in the directory with the other mount helpers.
