 Fun, right?  A poor man's instant VPN, and you don't even have to have
 admin access on the server.
 
+Sudoers File
+------------
+sshuttle can auto-generate the proper sudoers.d file using the current user 
+for Linux and OSX. Doing this will allow sshuttle to run without asking for
+the local sudo password and to give users who do not have sudo access
+ability to run sshuttle.
+
+  sshuttle --sudoers
+
+DO NOT run this command with sudo, it will ask for your sudo password when
+it is needed.
+
+A costume user or group can be set with the :
+option:`sshuttle --sudoers --sudoers-username {user_descriptor}` option. Valid
+values for this vary based on how your system is configured. Values such as 
+usernames, groups pre-pended with `%` and sudoers user aliases will work. See
+the sudoers manual for more information on valid user specif actions.
+The options must be used with `--sudoers`
+
+  sshuttle --sudoers --sudoers-user mike
+  sshuttle --sudoers --sudoers-user %sudo
+
+The name of the file to be added to sudoers.d can be configured as well. This
+is mostly not necessary but can be useful for giving more than one user
+access to sshuttle. The default is `sshuttle_auto`
+
+  sshuttle --sudoer --sudoers-filename sshuttle_auto_mike
+  sshuttle --sudoer --sudoers-filename sshuttle_auto_tommy
+
+You can also see what configuration will be added to your system without
+modifying anything. This can be helpfull is the auto feature does not work, or
+you want more control. This option also works with `--sudoers-username`.
+`--sudoers-filename` has no effect with this option.
+
+  sshuttle --sudoers-no-modify
+
+This will simply sprint the generated configuration to STDOUT. Example
+
+  08:40 PM william$ sshuttle --sudoers-no-modify
