-Use **one** of the following approaches:
-
-* Configure Kestrel in `Startup.ConfigureServices`:
-
-  1. Inject an instance of `IConfiguration` into the `Startup` class. The following example assumes that the injected configuration is assigned to the `Configuration` property.
-  2. In `Startup.ConfigureServices`, load the `Kestrel` section of configuration into Kestrel's configuration:
-
-     ```csharp
-     using Microsoft.Extensions.Configuration
-
-     public class Startup
-     {
-         public Startup(IConfiguration configuration)
-         {
-             Configuration = configuration;
-         }
-
-         public IConfiguration Configuration { get; }
-
-         public void ConfigureServices(IServiceCollection services)
-         {
-             services.Configure<KestrelServerOptions>(
-                 Configuration.GetSection("Kestrel"));
-         }
-
-         public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
-         {
-             ...
-         }
-     }
-     ```
-
-* Configure Kestrel when building the host:
-
-  In `Program.cs`, load the `Kestrel` section of configuration into Kestrel's configuration:
-
-  ```csharp
-  // using Microsoft.Extensions.DependencyInjection;
-
-  public static IHostBuilder CreateHostBuilder(string[] args) =>
-      Host.CreateDefaultBuilder(args)
-          .ConfigureServices((context, services) =>
-          {
-              services.Configure<KestrelServerOptions>(
-                  context.Configuration.GetSection("Kestrel"));
-          })
-          .ConfigureWebHostDefaults(webBuilder =>
-          {
-              webBuilder.UseStartup<Startup>();
-          });
-  ```
-
-Both of the preceding approaches work with any [configuration provider](xref:fundamentals/configuration/index).
