 -  ``--setup-dir``: path to the :term:`Setup` to check to status for. Not
    required if :term:`BBPATH` is already configured.
 
+-  ``--url``: URL from where to fetch the buildtools SDK installer, not
+   including filename. Requires ``--filename``. Overrides the value from the
+   configuration file.
+
+-  ``--filename``: filename of the buildtools installer. Requires ``--url``.
+   Overrides the value from the configuration file.
+
+-  ``--sdk-name``: SDK name used in the environment setup script installed
+   by the buildtools tarball (e.g. ``customsdk`` for
+   ``environment-setup-<arch>-customsdk-linux``). Defaults to ``pokysdk``.
+   Overrides the value from the configuration file.
+
+-  ``--no-check``: disable checksum validation when the server does not
+   provide a ``.sha256sum`` file alongside the installer. Checksum
+   validation is enabled by default.
+
+The ``url``, ``filename``, ``sdk-name`` and ``no-check`` options can also be
+set in the :term:`Configuration File` under the ``bitbake-setup`` section::
+
+   "bitbake-setup": {
+       "install-buildtools": {

+       },
+       "configurations": [ ... ]
+   }
+
+CLI arguments take precedence over values in the configuration file.
+Note that setting ``no-check`` to ``false`` in the configuration file has no
+effect; omit the key to use the default (enabled).
