@ -156,7 +156,8 @@ Set Up a Toolchain
In some specific configurations like non-MCU x86 targets on Linux,
you may be able to re-use the native development tools provided by
your operating system instead of an SDK by setting
``ZEPHYR_TOOLCHAIN_VARIANT=host``.
``ZEPHYR_TOOLCHAIN_VARIANT=host`` for gcc or
``ZEPHYR_TOOLCHAIN_VARIANT=llvm`` for clang.
If you want, you can use the SDK host tools (such as OpenOCD) with a
different toolchain by keeping the :envvar:`ZEPHYR_SDK_INSTALL_DIR`
