+# Results.Json
+
+Package contains code to help serialize and deserialize Result objects to and from JSON.
+`JsonConverterFactoryForResultOfT` is a `JsonConverterFactory` that can create `JsonConverter` objects for any `Result<T>` object.
+Remember, a Result representing one or more Errors contains a list of objects implementing the `IError` interface.
+The actual type of an Error object is not included when serialized. This means, that when deserializing that Error again, it can't be deserialized to its original type.
+Instead, the Error object is deserialized to a generic `DeserializedError` object.
+
+A serialized _Successful_ `Result<T>` will look like this:
+```json
+{
+  "Success": true,
+  "Value": "Some value"
+}
+```
+A serialized _Successful_ `Result<Unit>` will look like this:
+```json
+{
+  "Success": true
+}
+```
+A serialized _Error_ `Result<T>` or `Result<Unit>` will look like this:
+```json
+{
+  "Success": false,
+  "Errors": [
+	{
+	  "Type": "MyError",
+	  "Message": "Some error message"
+	  "Data": {
+		"Key": "value",
+	  }
+	}
+  ]
+}
+```
