+# desktop-bluray-player
+
+## Description
+
+This Ansible role installs and configures all the software required for Blu-ray playback on Arch Linux–based systems. It ensures that VLC and the necessary libraries for Blu-ray disc decryption and playback (`libaacs`, `libbluray`) are present, and provides hooks for optional AUR packages.
+
+## Overview
+
+- Uses the `community.general.pacman` module to install:
+  - `vlc` (media player with Blu-ray support)  
+  - `libaacs` (AACS decryption library)  
+  - `libbluray` (Blu-ray playback support library)  
+- Contains commented-out tasks for optional AUR packages (`aacskeys`, `libbdplus`) you can enable as needed.
+- Designed for idempotent execution on Arch Linux and derivatives.
+
+## Features
+
+- **VLC Installation**  
+  Installs `vlc` for general media and Blu-ray playback.
+
+- **AACS & BD+ Support**  
+  Installs `libaacs` and `libbluray` to handle Blu-ray disc encryption and playback.
+
+- **Optional AUR Packages**  
+  Drop-in tasks for `aacskeys` and `libbdplus` via AUR (commented out by default).
+
+- **Idempotent Role**  
+  Safe to run multiple times without unintended side effects.
+
+- **Arch Linux–Optimized**  
+  Leverages Pacman for fast and reliable package management.
