 ## Build APIs in 5 minutes not weeks
 
-GraphJin gives you an instant secure and fast GraphQL API without code. Just use a GraphQL query to define your API and GraphJin automagically converts it into a full featured API. Build your backend APIs **100X** faster. Works with **NodeJS** and **GO**. Supports several databases, **Postgres**, **MySQL**, **Yugabyte**, **AWS Aurora/RDS** and **Google Cloud SQL**
+Just use a simple GraphQL query to define your API and GraphJin automagically converts it into SQL and fetches the data you need. Build your backend APIs **100X** faster. Works with **NodeJS** and **GO**. Supports several databases, **Postgres**, **MySQL**, **Yugabyte**, **AWS Aurora/RDS** and **Google Cloud SQL**
+
+The following GraphQL query fetches a list of products, their owners, and other category information, including a cursor for retrieving more products. 
+GraphJin would do auto-discovery of your database schema and relationships and generate the most efficient single SQL query to fetch all this data including a cursor to fetch the next 20 times. You don't have to do a single thing besides write the GraphQL query. 
+
+```graphql
+query getProducts {
+  products(
+    # returns only 20 items
+    limit: 20
+
+    # orders the response items by highest price
+    order_by: { price: desc }
+
+    # only items with a price >= 20 and < 50 are returned
+    where: { price: { and: { greater_or_equals: 20, lt: 50 } } }
+  ) {
+    id
+    name
+    price
+
+    # also fetch the owner of the product
+    owner {
+      full_name
+      picture: avatar
+      email
+
+      # and the categories the owner has products under
+      category_counts(limit: 3) {
+        count
+        category {
+          name
+        }
+      }
+    }
+
+    # and the categories of the product itself
+    category(limit: 3) {
+      id
+      name
+    }
+  }
+  # also return a cursor that we can use to fetch the next
+  # batch of products
+  products_cursor
+}
+```
