+The contents of a :ref:`standard <sdk-manual/using:Using the Standard SDK>` or
+:ref:`extensible <sdk-manual/extensible:Using the extensible SDK>` SDK generated by
+the :term:`OpenEmbedded Build System` can be controlled by the
+:term:`SDK_FEATURES` variable that you typically configure in the image recipe
+for which the :ref:`ref-tasks-populate_sdk` or :ref:`ref-tasks-populate_sdk_ext`
+task is run.
+
+The SDK features available are:
+
+-  ``go``: add `Go` utilities for building `Go`-based applications.
+
+-  ``kernel-src``: adds the Linux kernel source tree to the SDK.
+
+-  ``rust``: add `Rust` utilities for building `Rust`-based applications.
