+# Shell 🐚
+
+## Description
+
+This Ansible role ensures that [.profile](https://en.wikipedia.org/wiki/Bourne_shell#Startup_scripts) is sourced in both [Bash](https://www.gnu.org/software/bash/) and [Zsh](https://www.zsh.org/) environments. It enables consistent environment variable loading across different login shells by linking shell-specific profile files (`.bash_profile`, `.zprofile`) to a centralized `.profile`.
+
+## Overview
+
+By standardizing `.profile` as the central source for environment configuration, this role ensures consistent shell behavior. It does **not** manage the contents of `.profile` itself — only guarantees that it is sourced by supported shells.
+
+## Purpose
+
+The purpose of this role is to unify shell environment setup across Bash and Zsh. It minimizes duplication and confusion by encouraging the use of `.profile` for shared configuration such as environment variables and agent settings.
+
+## Features
+
+- **Centralized Configuration:** Promotes `.profile` as the single source for shared shell settings.
+- **Cross-Shell Compatibility:** Ensures both Bash and Zsh source `.profile` properly.
+- **Non-Invasive:** Does not alter the content of `.profile`.
