-
-   The ISSM toolset only supports development for Intel |reg| Quark |trade|
-   Microcontrollers, for example, the Arduino 101 board.  (Check out the
-   "Zephyr Development Environment
-   Setup" in this `Getting Started on Arduino 101 with ISSM`_ document.)
-   Additional setup is required to use the ISSM GUI for development.
-
-#. Install the ISSM toolchain by downloading it from the Intel Developer Zone's
-   `ISSM Toolchain`_ downloads page, then extracting the archive somewhere on
-   your system.
-
-   .. warning::
-
-      Like the Zephyr repository, do not install the toolchain in a directory
-      with spaces anywhere in the path.
-
-#. :ref:`Set these environment variables <env_vars>`:
-
-   - Set :envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``issm``.
-   - Set :envvar:`ISSM_INSTALLATION_PATH` to the directory containing the
-     extracted files.
-
-#. To check that you have set these variables correctly in your current
-   environment, follow these example shell sessions (the
-   :envvar:`ISSM_INSTALLATION_PATH` values may be different on your system):
-
-   .. code-block:: console
-

-      $ echo $ZEPHYR_TOOLCHAIN_VARIANT
