 ## Define properties[#define]
 
-This section adds the `properties` keyword. In JSON Schema terms, `properties` is a [validation keyword](https://json-schema.org/draft/2020-12/json-schema-core.html#section-10.3.2.1). When you define `properties`, you create an object where each property represents a key in the JSON data that’s being validated. You can also specify which properties defined in the object are required.
+`Properties` is a [validation keyword](https://json-schema.org/draft/2020-12/json-schema-core.html#section-10.3.2.1) used to define the keys expected in the json document. Here, we expect a JSON document used to define products. The keys expected are the `productId`, `productName`, `price`, and `tags`. These keys would have corresponding values of which the `productId` should have a value of integer type, the `productName` should have a string type value, the `price` key should have a number type value, and the `tags` should have an array as value. These all make up the `Product` object.
 
-### Add the properties object[#properties]
+It is defines a series of property objects. A  `required` key with an array of values that tells which of the properties are required. This key is added anywhere inside the schema object, but outside the `properties` object.
 
-Using the product catalog example, `productId` is a numeric value that uniquely identifies a product. Since this is the canonical identifier for the product, it’s required.

-1. Add the `properties` validation keyword to the end of the schema:

+    "price": {},
+
+    "tags": {}
+
+  },
+
+  "required": [ "productId", "productName", "price" ]
 ```
 
-2. Add the `productId` keyword, along with the following schema annotations:
-    * `description`: describes what `productId` is. In this case, it’s the product’s unique identifier.
-    * `type`: defines what kind of data is expected. For this example, since the product identifier is a numeric value, use `integer`.
+### Add necessary information to the property definitions
 
+Add the description and type information to `productId` and `productName` in the `properties` object.
 
 ```jsonc

-  "properties": {
-    "productId": {
-      "description": "The unique identifier for a product",
-      "type": "integer"

-With the new `properties` validation keyword, the overall schema looks like this:

-      "description": "The unique identifier for a product",
-      "type": "integer"
-    }
-  }
-}
-```
+    "productId": {
 
-The following example adds another required key, `productName`. This value is a string:
+      "description":"The unique identifier for the product",
 
-```json
-{
-  "$schema": "https://json-schema.org/draft/2020-12/schema",

-      "type": "string"
-    }
-  }
-}
-```
+      "type":"integer"
+
+    },
 
-The `properties` object now includes two keys, `productId` and `productName`. When JSON data is validated against this schema, validation fails for any documents that contain invalid data in either of these fields.
