@@ -13,12 +27,25 @@ DBIx::Class::Storage::DBI::Sybase - Storage::DBI subclass for Sybase
 
 =head1 SYNOPSIS
 
-This subclass supports L<DBD::Sybase>.
+This subclass supports L<DBD::Sybase> for real Sybase databases.  If
+you are using an MSSQL database via L<DBD::Sybase>, see
+L<DBIx::Class::Storage::DBI::Sybase::MSSQL>.
+
+=head1 CAVEATS
+
+This storage driver uses L<DBIx::Class::Storage::DBI::NoBindVars> as a base.
+This means that bind variables will be interpolated (properly quoted of course)
+into the SQL query itself, without using bind placeholders.
+
+More importantly this means that caching of prepared statements is explicitly
+disabled, as the interpolation renders it useless.
