 title: Your First Schema 
-description: Welcome to the JSON Schema Tour! Create your first schema to validate a JSON document.
-keywords: type, properties, integer, string
+description: "JSON Schema is a language used for defining the structure and constraints of a JSON document. A JSON Schema is a JSON document that you can use to validate or document another JSON, which we call a JSON instance. JSON Schema is particularly useful in scenarios where data needs to be validated against a predefined structure. This ensures data consistency and helps prevent errors in applications that consume or produce JSON data. It's also valuable for documenting the expected format of JSON data, making it easier for developers to understand and work with APIs and data structures. JSON Schema supports a wide range of validation rules, including data types, formats, ranges, and dependencies between properties."
