    {
        //get settigns as object from config
        var someSettings= Configuration.GetSection(typeof(SomeSettings).Name).Get<SomeSettings>();                                                    
        //put settings into module constructor 
        builder.RegisterModule(new AutofacModule(someSettings));
    }
