+.Nd doas configuration file
+.Sh DESCRIPTION
+The
+.Xr doas 1
+utility executes commands as other users according to the rules
+configured in either the configuration file or, optionally, the
+configuration directory.  The preference to use the configuration
+file or configuration directory is determined at compile time,
+.Xr doas 1
+will only consult one or the other.
+.Pp
+Configuration snippets stored in the configuration directory
+follow the same rules as the classic
+.Xr doas 1
+configuration file, documented in
+.Xr doas.conf 5 .
+They must end with the .conf extension, or they will be ignored.
+.Pp
+These snippets are read in alphabetical order and thus can be
+ordered in the same way as other configuration directories.
