+
+However, it could be that you just want to get a @code{cgitrc} up and
+running.  In that case, you can pass an @code{opaque-cgit-configuration}
+as a record to @code{cgit-service-type}.  As its name indicates, an
+opaque configuration does not have easy reflective capabilities.
+
+Available @code{opaque-cgit-configuration} fields are:
+
+@deftypevr {@code{opaque-cgit-configuration} parameter} package cgit
+The cgit package.
+@end deftypevr
+
+@deftypevr {@code{opaque-cgit-configuration} parameter} string string
+The contents of the @code{cgitrc}, as a string.
+@end deftypevr
+
+For example, if your @code{cgitrc} is just the empty string, you
+could instantiate a cgit service like this:
+
+@example
+(service cgit-service-type
+         (opaque-cgit-configuration
+          (cgitrc "")))
+@end example
