-Template for Ansible roles
+ ansible role rtl_nic_firmware
+===============================
+
+Ansible role to deploy ``rtl_nic`` Firmware for APU.
+
+This role is only running at:
+```yaml
+when:
+  - ansible_board_name == 'APU'
+  - ansible_product_name == 'APU'
+```
+
+It will download the defined Firmware Files from the ``rtl_nic__firmware`` variable.
+Then we run ``update-initramfs -k all -u``.
+
+You can change the downloaded firmware file names by modifying the default variables.
