Adding multilanuages at plugin installation

Hi
I Create a new payment plugin for nopcommerce .and  at installation i add my local resources , kindly find example below:

   this.AddOrUpdatePluginLocaleResource("Plugins.Payments.SISOW.Fields.RedirectionTip", "You will be redirected to PayPal site to complete the order.");
            this.AddOrUpdatePluginLocaleResource("Plugins.Payments.SISOW.Fields.UseSandbox", "Use Sandbox");
            this.AddOrUpdatePluginLocaleResource("Plugins.Payments.SISOW.Fields.UseSandbox.Hint", "Check to enable Sandbox (testing environment).");
            this.AddOrUpdatePluginLocaleResource("Plugins.Payments.SISOW.Fields.BusinessEmail", "Business Email");


users will use that plugin may understand English or dutch or Germany ?? so I want to add the value in multi-language for each resource .
for example I want to add values for "Plugins.Payments.SISOW.Fields.RedirectionTip" in dutch and Germany not in English only .  and I want to do that at the plugin installation


Thanks
