+@cindex SMB
+The @code{(gnu services samba)} module provides service definitions for
+Samba as well as additional helper services.  Currently it provides the
+following services.
+
+@subsubheading Samba
+
+@uref{https://www.samba.org, Samba} provides network shares for folders
+and printers using the SMB/CIFS protocol commonly used on Windows.  It
+can also act as an Active Directory Domain Controller (AD DC) for other
+hosts in an heterougenious network with different types of Computer
+systems.
+
+@defvar {Scheme variable} samba-service-type
+
+The service type to enable the samba services @code{samba}, @code{nmbd},
+@code{smbd} and @code{winbindd}.  By default this service type does not
+run as an AD DC, hence @code{samba} remains disabled.
+
+@end defvar
+
+@deftp{Data Type} samba-service-configuration
+Configuration record for the Samba suite.
+
+@table @asis
+@item @code{package} (default: @code{samba})
+The samba package to use.
+
+@item @code{config-file} (default: @code{#f})
+The config file to use.
