+Implement Schema Validation
+---------------------------
+
+You can use the ``jsonSchema()`` method to implement :manual:`schema
+validation </core/schema-validation/>` when using the following schema
+builder methods:
+
+- ``Schema::create()``: When creating a new collection
+- ``Schema::table()``: When updating collection properties
+
+You can use schema validation to restrict data types and value ranges of
+document fields in a specified collection. After you implement schema
+validation, the server restricts write operations that don't follow the
+validation rules.
+
+You can pass the following parameters to ``jsonSchema()``:
+
+- ``schema``: Array that specifies the validation rules for the
+  collection. To learn more about constructing a schema, see
+  the :manual:`$jsonSchema </reference/operator/query/jsonSchema/>`
+  reference in the {+server-docs-name+}.
+
+- ``validationLevel``: Sets the level of validation enforcement.
+  Accepted values are ``"strict"`` (default) and ``"moderate"``.
+
+- ``validationAction``: Specifies the action to take when invalid
+  operations are attempted. Accepted values are ``"error"`` (default) and
+  ``"warn"``.
+
+This example demonstrates how to specify a schema in the
+``jsonSchema()`` method when creating a collection. The schema
+validation has the following specifications:
+
+- Documents in the ``pilots`` collection must
+  contain the ``license_number`` field.
+
+- The ``license_number`` field must have an integer value between
+  ``1000`` and ``9999``.
+
+- If you attempt to perform invalid write operations, the server raises
+  an error.
