+The [geekoops-nc-system role](https://github.com/GeekOops/geekoops-nc-system) is an Ansible role to install and configure `nextcloud` on an openSUSE Leap server using the `nextcloud` system package and `apache2`. There is also the [geekoops-nextcloud role](https://github.com/GeekOops/geekoops-nextcloud) that is more complex and allows more customization.
+
+If desired, the role also installs and configures MariaDB with a custom database and user for you.
+
+# Example
+
+The following example playbook installs nextcloud and creates a `nextcloud` database and database user using the password `password123` (very secure!).
+
+
+```yaml
+---
+- hosts: jellyfish
+  user: root
+  
+  roles:
+     - role: geekoops-nc-system
+       vars:
+         db_configure: true
+         db_name: 'nextcloud'
+         db_user: 'nextcloud'
+         db_pass: 'password123'
+         firewall_configure: true
+         firewall_zone: 'public'
+```
