+# Ansible Playbooks
+
+This directory contains Ansible playbooks for automating server configuration and management tasks.
+
+## Playbooks
+
+- **apt_upgrade.yml**: This playbook updates all packages on a Debian/Ubuntu server.
+- **zabbix_agent_upgrade.yml**: This playbook upgrades the Zabbix agent on a server.
+
+## Usage
+
+To use these playbooks, you will need to have Ansible installed on your control machine. You will also need to have an inventory file that defines the hosts you want to manage.
+
+Once you have Ansible and an inventory file set up, you can run a playbook using the following command:
+
+```
+ansible-playbook -i <inventory_file> <playbook>.yml
+```
