-# See smb.conf.example for a more detailed config file or
-# read the smb.conf manpage.
-# Run 'testparm' to verify the config is correct after
-# you modified it.
 #
-# Note:
+# Sample configuration file for the Samba suite for Debian GNU/Linux.
-# SMB1 is disabled by default. This means clients without support for SMB2 or
+#
-# SMB3 are no longer able to connect to smbd (by default).
+#
+# This is the main Samba configuration file. You should read the
+# smb.conf(5) manual page in order to understand the options listed
+# here. Samba has a huge number of configurable options most of which
+# are not shown in this example
+#
+# Some options that are often worth tuning have been included as
+# commented-out examples in this file.
+#  - When such options are commented with ";", the proposed setting
+#    differs from the default Samba behaviour
+#  - When commented with "#", the proposed setting is the default
+#    behaviour of Samba but the option is considered important
+#    enough to be mentioned here
+#
+# NOTE: Whenever you modify this file you should run the command
+# "testparm" to check that you have not made any basic syntactic
+# errors.
