+# Persona: Developer – Shell 🐚
+
+## Description
+
+This Ansible role sets up a minimal yet effective environment for Bash and shell script development on Arch Linux. It includes tools like `shellcheck` that help developers write clean, maintainable, and error-free shell scripts.
+
+Learn more about [ShellCheck](https://www.shellcheck.net/), [Bash](https://www.gnu.org/software/bash/), and general shell scripting via the [Arch Wiki - Bash](https://wiki.archlinux.org/title/Bash).
+
+## Overview

+This role expands the general `persona-developer` by equipping the system with tools specifically aimed at writing and linting shell scripts. It's ideal for DevOps engineers, system administrators, and anyone automating systems with Bash.
+
+## Purpose
+
+The role ensures that the developer can safely and efficiently write shell scripts, catching bugs and stylistic issues early using static analysis.
+
+## Features
+
+- **Installs ShellCheck:** A linting tool for detecting issues in shell scripts.
+- **Persona Integration:** Extends the general developer persona for Bash-centric workflows.
+- **Lightweight & Fast:** Quick setup with room for future extensions.
+
+## Customization
