+@subsection Changing the default remote shell
+@cindex zsh setup
+
+Per default, @value{tramp} uses the command @command{/bin/sh} for
+strting a shell on the remote host.  This can be changed by setting
+the connection property @option{remote-shell}, see @xref{Predefined
+connection information}.  Other properties might be adapted as well,
+like @option{remote-shell-login} or @option{remote-shell-args}.  If
+you want, for example, use @command{/usr/bin/zsh} on a remote host,
+you might apply
+
+@lisp
+@group
+(add-to-list 'tramp-connection-properties

+                   "remote-shell" "/usr/bin/zsh"))
+@end group
+@end lisp
+
+This approach has also the advantage, that settings in
+@code{tramp-sh-extra-args} will be applied.  For zsh, the trouble
+with the shell prompt due to set zle options will be avoided.
