+## Custom Metadata Examples
+
+You can now customize the Example Objects used in the metadata pages with the new `CreateExampleObjectFn` property on the `MetadataFeature` plugin which you can customize like:
+
+```csharp
+services.ConfigurePlugin<MetadataFeature>(feature => {
+    feature.CreateExampleObjectFn = type => {
+        if (type == typeof(CreateJob))
+        {
+            return new CreateJob {
+                Title = "Example Job",
+                Company = "Acme",
+                Description = "Job Description",
+                SalaryRangeLower = 50_000,
+                SalaryRangeUpper = 100_000,
+            };
+        }
+        if (type == typeof(Job))
+        {
+            return new Job {
+                Id = 1,
+                Description = "Job Description",
+                Company = "Acme",
+                SalaryRangeLower = 50_000,
+                SalaryRangeUpper = 100_000,
+                CreatedBy = "Admin",
+                CreatedDate = DateTime.UtcNow.Date,
+            };
+        }
+        return null; // default behavior
+    };
+});
+```
+
+This will use these example objects in the [metadata pages](/metadata-page) instead of the default auto-generated examples.
