+# Python-Yaml
+
+## Description
+
+This Ansible role installs the **python-yaml** package on the target system. It ensures that the Python `yaml` library is available for loading and processing YAML files.
+
+## Overview
+
+Optimized for simplicity and idempotency, this role provides:
+- Installation of the `python-yaml` package via the Pacman package manager.
+- A mechanism to run the installation only once.
+
+## Purpose
+
+The purpose of this role is to reliably provide the Python-YAML package so that Python scripts can work with YAML files.
+
+## Features
+
+- **YAML Support:** Installs the `python-yaml` package, which supplies the `yaml` library for Python.  
+- **Idempotency:** Uses a fact to ensure that the installation runs only on the first execution.
