 # MAAS-ansible-playbook
 An Ansible playbook for installing and configuring MAAS, further documentation is found [here](https://maas.io/docs/ansible-playbooks-reference).
+This was forked from: git clone [email protected]:maas/maas-ansible-playbook as the upstream playbook is no longer supported by ansible
 
 ## Versions
 This playbook has been tested with Ansible version 5.10.0 and above. We recommend using the latest available stable version of Ansible (currently 7.x). The `netaddr` Python library needs to be installed on the machine on which Ansible is used; note that this is not required on remote hosts.
 
 ## Install
 
 ```
-git clone [email protected]:maas/maas-ansible-playbook
+git clone [email protected]:singlestore/maas-ansible-playbook
 ```
