+### Automated OS Installation for Dell iDRAC Systems
+
+For completely automating the installation using an Ubuntu auto install ISO image see [here](auto_install_ubuntu_iso.md).
+
+The Ansible playbook [install_os.yml](../ansible/install_os.yml) will help automate the installation of an Operating System on Dell servers using iDRAC, dellemc.openmanage library and the autoinstall Ubuntu iso that we have created. This script currently supports the dell machines only.
+
+Currently, the `idrac_os_deployment` ansible role natively supports installation of `RHEL` and `ESXI` Operating Systems or using a `Custom ISO`. We are using the custom iso option, to install `Ubuntu Jammy 22.04` OS on our systems.
+
+Fore more details on the dellemc.openmanage idrac_os_deployment ansible role that was used in the playbook, refer the documentation [here](https://github.com/dell/dellemc-openmanage-ansible-modules/tree/collections/roles/idrac_os_deployment).
+
+Progress on native `UBUNTU` support to the `idrac_os_deployment` ansible role can be tracked [here](https://github.com/dell/dellemc-openmanage-ansible-modules/pull/784).
+
+To run the playbook:
+
+```bash
+ansible-playbook -i inventory install_os.yml
