+# Hostname
+
+This Ansible role ensures that the target host’s system hostname is set to the inventory hostname.
+
+## Description
+
+- Uses the built-in `hostname` module to apply the `inventory_hostname` value  
+- Idempotent: only changes the system name if it differs  
+- No external dependencies
+
+## Overview
+
+1. **Task**  
+   - `set hostname to {{ inventory_hostname }}`  
+     Applies the desired hostname.
+2. **Module**  
+   - Leverages Ansible’s [`hostname`](https://docs.ansible.com/ansible/latest/collections/ansible/builtin/hostname_module.html) module.
+
+## Features
+
+* Simple and lightweight
+* Automatically adapts to your inventory names
+* Safe to run repeatedly
