@@ -7,12 +7,8 @@ Zephyr provides several :ref:`west extension commands <west-extensions>` for
 building, flashing, and interacting with Zephyr programs running on a board:
 ``build``, ``flash``, ``debug``, ``debugserver`` and ``attach``.
 
-These use information stored in the CMake cache [#cmakecache]_ to
-flash or attach a debugger to a board supported by Zephyr. The exception is
-starting a clean build (i.e. with no previous artifacts) which will in fact
-run CMake thus creating the corresponding cache.
-The CMake build system commands with the same names (i.e. all but ``build``)
-directly delegate to West.
+For information on adding board support for the flashing and debugging
+commands, see :ref:`flash-and-debug-support` in the board porting guide.
