+The kernel has experimental support for the Rust programming language
+[rust-language]_ under ``CONFIG_RUST``. It is compiled with ``rustc`` [rustc]_
+under ``--edition=2021`` [rust-editions]_. Editions are a way to introduce
+small changes to the language that are not backwards compatible.
+
+On top of that, some unstable features [rust-unstable-features]_ are used in
+the kernel. Unstable features may change in the future, thus it is an important
+goal to reach a point where only stable features are used.
