+## The `computed_field` decorator
+
+??? api "API Documentation"
+    [`pydantic.fields.computed_field`][pydantic.fields.computed_field]<br>
+
+The `computed_field` decorator can be used to include `property` or `cached_property` attributes when serializing a
+model or dataclass. This can be useful for fields that are computed from other fields, or for fields that
+are expensive to computed (and thus, are cached).
 
 Here's an example:
 
 ```py
-from pydantic import BaseModel, EmailStr, Field, SecretStr
+from pydantic import BaseModel, computed_field
 
 
-class User(BaseModel):
-    age: int = Field(description='Age of the user')
-    email: EmailStr = Field(examples=['marcelo@mail.com'])
-    name: str = Field(title='Username')
-    password: SecretStr = Field(
-        json_schema_extra={
-            'title': 'Password',
-            'description': 'Password of the user',
-            'examples': ['123456'],
