+NVUE Switch
+===========
+
+This role configures Cumulus switches using the `nvidia.nvue.command` Ansible
+module. It provides a fairly minimal abstraction of the configuration interface
+provided by the `nvidia.nvue.command` module, allowing for application of
+arbitrary switch configuration options.
+
+Requirements
+------------
+
+The switches should be configured to allow SSH access.
+
+Role Variables
+--------------
+
+`nvue_switch_config` is a list of NVUE commands to apply to the switch, and
+defaults to an empty list. Commands must be formatted without the `nv` prefix,
+which is added by the `nvidia.nvue.command` module before execution on the
+switch.
+
+`nvue_switch_interface_config` contains interface configuration. It is a dict
+mapping switch interface names to configuration dicts. Interfaces can be switch
+physical interfaces, but also special interfaces such as bridges or bonds. Each
+dict may contain the following items:
+
+- `description` - a description to apply to the interface.
+- `config` - a list of per-interface configuration, each applied with a `nv
+  set interface <interface-name>` prefix.
+
+Dependencies
+------------
+
+None
+
+Example Playbook
+----------------
+
+The following playbook configures hosts in the `nvue-switches` group. It
+applies global configuration to configure a BGP AS and add two EBGP neighbors
+using BGP Unnumbered, enables two host interfaces with jumbo frames, and
+attaches them to a traditional bridge called `bridge1` configured with an IP
+address.
