 Appending kernel parameters to boot instances
 =============================================
 
-The Bare Metal service supports passing custom kernel parameters to boot instances to fit
-users' requirements. The way to append the kernel parameters is depending on how to boot instances.

-Network boot
-------------
-Currently, the Bare Metal service supports assigning unified kernel parameters to PXE
-booted instances by:
-
-* Modifying the ``[pxe]/pxe_append_params`` configuration option, for example::
-
-    [pxe]
-
-    pxe_append_params = quiet splash
-
-* Copying a template from shipped templates to another place, for example::
-
-    https://git.openstack.org/cgit/openstack/ironic/tree/ironic/drivers/modules/pxe_config.template
-
-  Making the modifications and pointing to the custom template via the configuration
-  options: ``[pxe]/pxe_config_template`` and ``[pxe]/uefi_pxe_config_template``.
+The `Appending kernel parameters to boot instances`_ section has been moved
+to the Bare Metal service Install Guide.
 
-Local boot
-----------
-For local boot instances, users can make use of configuration drive
-(see `Enabling the configuration drive (configdrive)`_) to pass a custom
-script to append kernel parameters when creating an instance. This is more
-flexible and can vary per instance.
-Here is an example for grub2 with ubuntu, users can customize it
-to fit their use case:
-
-    .. code:: python
-
-     #!/usr/bin/env python
-     import os
-
-     # Default grub2 config file in Ubuntu
-     grub_file = '/etc/default/grub'
-     # Add parameters here to pass to instance.
-     kernel_parameters = ['quiet', 'splash']
-     grub_cmd = 'GRUB_CMDLINE_LINUX'
-     old_grub_file = grub_file+'~'
-     os.rename(grub_file, old_grub_file)
-     cmdline_existed = False
-     with open(grub_file, 'w') as writer, \
-            open(old_grub_file, 'r') as reader:
-            for line in reader:
-                key = line.split('=')[0]
