 This is particularly a problem for the toolchain (i.e. LLVM/clang and Rust).
-Because meta-clang's kirkstone branch currently only provides clang 14, we are
-unable to support Chromium versions higher than 120 due to those versions
-requiring a more recent clang version. Also, kirkstone users **must** ensure the
-following:
-* Chromium needs a somewhat recent version of Rust, and for that
-  meta-lts-mixins' **kirkstone/rust-1.68** or **kirkstone/rust-1.70** branch
-  needs to be used.
+
+* Chromium needs a more recent version of Rust than OE Core provides for
+  kirkstone, which is why we depend on meta-lts-mixins' `kirkstone/rust` branch.
+
+* Chromium needs at least clang 18, but meta-clang's kirkstone branch provides
+  clang 14. Thus, we depend on meta-clang's `kirkstone-clang18` branch.
