-DETAILED INFO
+**minishell** is a minimal bash-like shell implementation written in C. It provides essential shell functionality including command execution, piping, input/output redirection, and built-in commands.
+
+### Key Features
+
+- **Command Execution**: Execute external programs with argument parsing and path resolution.
+- **Pipelines**: Connect multiple commands using the pipe operator (`|`).
+- **Redirections**: Support for input (`<`), output (`>`), and append (`>>`) file redirections.
+- **Built-in Commands**: `cd`, `echo`, `env`, `exit`, `export`, `pwd`, `unset`.
+- **Environment Variables**: Access and manage shell environment variables.
+- **Interactive Shell**: Read-Evaluate-Print Loop (REPL) powered by GNU Readline.
+- **Quote Handling**: Proper handling of single and double quotes for literal strings.
+
+### Development
+
+The codebase adheres to **Norminette v4** standards and uses a modular architecture separating parsing, execution, and built-in command logic. Build artifacts are automatically generated; refer to `AGENTS.md` for detailed development guidelines.
