 # Community.Extensions.Spectre.Cli.Hosting
 Extension methods and a bit of fancy footwork to host Spectre.Console.Cli in a HostApplicationBuilder
+
+```
+
+var builder = Host.CreateApplicationBuilder(args);
+
+// Add a command and optionally configure it.
+builder.Services.AddCommand<HelloCommand>("hello", cmd =>
+{
+    cmd.WithDescription("A command that says hello");
+});
+
+
+// Add another command and its dependent service
+
+builder.Services.AddCommand<OtherCommand>("other");
+builder.Services.AddScoped(s => new SampleService("Other Service"));
+
+//
+// The standard call save for the commands will be pre-added & configured
+//
+builder.UseSpectreConsole<HelloCommand>(config =>
+{
+    // All commands above are passed to config.AddCommand() by this point
+
+#if DEBUG
+    config.PropagateExceptions();
+    config.ValidateExamples();
+#endif
+    config.SetApplicationName("hello");
+    config.UseBasicExceptionHandler();
+});
+
+var app = builder.Build();
+await app.RunAsync();
+```
