+# Multi Language configuration
+
+
+## Registering services at Startup
+
+```csharp
+public Startup(IConfiguration configuration)
+{
+  Configuration = configuration;
+}
+
+public IConfiguration Configuration { get; }
+	
+public void ConfigureServices(IServiceCollection services)
+{
+    var supportedCultures = new[] { "en", "it" };
+    services.AddSupportedCultures(supportedCultures);
+}
+
+//OMISSIS
+
+public void Configure(WebApplication app)
+{
+    app.UseLocalizationConfiguration();
+}
+```
+
+<b>Note:</b> The supportedCultures values can be changed to suit your needs.
+
+But remember to create the resx files of the supported languages in the resources folder, setting the access modifier to Public.
