 Due to `JsonNode` implicit operators, this makes initialization sometimes easier, instead of:

+{
+    In = null,
+    Name = "username",
+    Description = "username to fetch",

 the assignment becomes simply,
 
 ```csharp
-                    Example = 0.5f,
+    Example = 0.5f,
 ```
 
 For a more complex example, where the developer wants to create an extension that is an object they would do this in v1:
 
 ```csharp
-    var openApiObject = new OpenApiObject
-            {
-                {"stringProp", new OpenApiString("stringValue1")},
-                {"objProp", new OpenApiObject()},
-                {
-                    "arrayProp",
-                    new OpenApiArray
-                    {
-                        new OpenApiBoolean(false)
-                    }
-                }
-            };
-    var parameter = new OpenApiParameter();
-    parameter.Extensions.Add("x-foo", new OpenApiAny(openApiObject));
+var openApiObject = new OpenApiObject
+{
+    {"stringProp", new OpenApiString("stringValue1")},
+    {"objProp", new OpenApiObject()},
+    {
+        "arrayProp",
+        new OpenApiArray
+        {
+            new OpenApiBoolean(false)
+        }
+    }
+};
+var parameter = new OpenApiParameter();
+parameter.Extensions.Add("x-foo", new OpenApiAny(openApiObject));
 
 ```
 
 In v2, the equivalent code would be,
 
 ```csharp
-   var openApiObject = new JsonObject

-                    new JsonArray
-                    {
-                        false

-    var parameter = new OpenApiParameter();

 #### Summary and Description alongside $ref
 
 Through the use of proxy objects in order to represent references, it is now possible to set the Summary and Description property on an object that is a reference. This was previously not possible.
 
 ```csharp
-    var parameter = new OpenApiParameterReference("id", hostdocument)
-    {
-        Description = "Customer Id"
-    };
+var parameter = new OpenApiParameterReference("id", hostdocument)
