+#### Example
+
+The following example demonstrates the use of the `TraceEnricherHook` with the `OpenFeature dotnet-sdk`. The traces are sent to a `jaeger` OTLP collector running at `localhost:4317`.
+
+```csharp
+using OpenFeature.Contrib.Providers.Flagd;
+using OpenFeature.Hooks;
+using OpenTelemetry.Exporter;
+using OpenTelemetry.Resources;
+using OpenTelemetry;
+using OpenTelemetry.Trace;
+
+namespace OpenFeatureTestApp
+{
+    class Hello {
+        static void Main(string[] args) {
+
+            // set up the OpenTelemetry OTLP exporter
+            var tracerProvider = Sdk.CreateTracerProviderBuilder()
+                    .AddSource("my-tracer")
+                    .ConfigureResource(r => r.AddService("jaeger-test"))
+                    .AddOtlpExporter(o =>
+                    {
+                        o.ExportProcessorType = ExportProcessorType.Simple;
+                    })
+                    .Build();
+
+            // add the TraceEnricherHook to the OpenFeature instance
+            OpenFeature.Api.Instance.AddHooks(new TraceEnricherHook());
+
+            var flagdProvider = new FlagdProvider(new Uri("http://localhost:8013"));
+
+            // Set the flagdProvider as the provider for the OpenFeature SDK
+            OpenFeature.Api.Instance.SetProvider(flagdProvider);
+
+            var client = OpenFeature.Api.Instance.GetClient("my-app");
+
+            var val = client.GetBooleanValueAsync("myBoolFlag", false, null);
+
+            // Print the value of the 'myBoolFlag' feature flag
+            System.Console.WriteLine(val.Result.ToString());
+        }
+    }
+}
+```
+
+After running this example, you will be able to see the traces, including the events sent by the hook in your Jaeger UI.
+
+### Metrics Hook
+
+For this hook to function correctly a global `MeterProvider` must be set.
+`MetricsHook` performs metric collection by tapping into various hook stages.
+
+Below are the metrics extracted by this hook and dimensions they carry:
+
+| Metric key                             | Description                     | Unit         | Dimensions                    |
+| -------------------------------------- | ------------------------------- | ------------ | ----------------------------- |
+| feature_flag.evaluation_requests_total | Number of evaluation requests   | request      | key, provider name            |
+| feature_flag.evaluation_success_total  | Flag evaluation successes       | impression   | key, provider name, reason    |
+| feature_flag.evaluation_error_total    | Flag evaluation errors          | 1            | key, provider name, exception |
+| feature_flag.evaluation_active_count   | Active flag evaluations counter | 1            | key, provider name            |
+
+Consider the following code example for usage.
+
+#### Example
+
+The following example demonstrates the use of the `MetricsHook` with the `OpenFeature dotnet-sdk`. The metrics are sent to the `console`.
+
+```csharp
+using OpenFeature.Contrib.Providers.Flagd;
+using OpenFeature;
+using OpenFeature.Hooks;
+using OpenTelemetry;
+using OpenTelemetry.Metrics;
+
+namespace OpenFeatureTestApp
+{
+    class Hello {
+        static void Main(string[] args) {
+
+            // set up the OpenTelemetry OTLP exporter
+            var meterProvider = Sdk.CreateMeterProviderBuilder()
+                    .AddMeter("OpenFeature")
+                    .ConfigureResource(r => r.AddService("openfeature-test"))
+                    .AddConsoleExporter()
+                    .Build();
+
+            // add the MetricsHook to the OpenFeature instance
+            OpenFeature.Api.Instance.AddHooks(new MetricsHook());
+
+            var flagdProvider = new FlagdProvider(new Uri("http://localhost:8013"));
+
+            // Set the flagdProvider as the provider for the OpenFeature SDK
+            OpenFeature.Api.Instance.SetProvider(flagdProvider);
+
+            var client = OpenFeature.Api.Instance.GetClient("my-app");
+
+            var val = client.GetBooleanValueAsync("myBoolFlag", false, null);
+
+            // Print the value of the 'myBoolFlag' feature flag
+            System.Console.WriteLine(val.Result.ToString());
+        }
+    }
+}
+```
+
+After running this example, you should be able to see some metrics being generated into the console.
