 The OpenFeature SDK logs to the `openfeature` logger using the `logging` package from the Python Standard Library.
 
-### Named clients
+### Domains
 
-Named clients are not yet available in the Python SDK. Progress on this feature can be tracked [here](https://github.com/open-feature/python-sdk/issues/125).
+Clients can be assigned to a domain.
+A domain is a logical identifier which can be used to associate clients with a particular provider.
+If a domain has no associated provider, the global provider is used.
+
+```python
+from openfeature import api
+
+# Registering the default provider
+api.set_provider(MyProvider());
+# Registering a provider to a domain
+api.set_provider(MyProvider(), "my-domain");
+
+# A client bound to the default provider
+default_client = api.get_client();
+# A client bound to the MyProvider provider
+domain_scoped_client = api.get_client("my-domain");
+```
+
+Domains can be defined on a provider during registration.
+For more details, please refer to the [providers](#providers) section.
