+## `MISSING` sentinel
+
+The `MISSING` sentinel is a singleton indicating a field value was not provided during validation.
+
+This singleton can be used as a default value, as an alternative to `None` when it has an explicit
+meaning. During serialization, any field with `MISSING` as a value is excluded from the output.
+
+```python
+from typing import Union
+
+from pydantic import BaseModel
+from pydantic.experimental.missing_sentinel import MISSING
+
+
+class Configuration(BaseModel):
+ timeout: Union[int, None, MISSING] = MISSING
+
+
+# configuration defaults, stored somewhere else:
+defaults = {'timeout': 200}
+
+conf = Configuration()
+
+# `timeout` is excluded from the serialization output:
+conf.model_dump()
+# {}
+
+# The `MISSING` value doesn't appear in the JSON Schema:
+Configuration.model_json_schema()['properties']['timeout']
+#> {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Timeout'}}
+
+
+# `is` can be used to discrimate between the sentinel and other values:
+timeout = conf.timeout if conf.timeout is not MISSING else defaults['timeout']
+```
+
+This feature is marked as experimental because it relies on the draft [PEP 661](https://peps.python.org/pep-0661/), introducing sentinels in the standard library.
+
+As such, the following limitations currently apply:
+
+* Static type checking of sentinels is only supported with Pyright
+ [1.1.402](https://github.com/microsoft/pyright/releases/tag/1.1.402)
+ or greater, and the `enableExperimentalFeatures` type evaluation setting
+ should be enabled.
+* Pickling of models containing `MISSING` as a value is not supported.
