+# Minishell
+
+Minishell is a 42 School project that involves creating a minimalistic shell in C language. The shell should be able to handle basic commands, manage environment variables and implement several built-in functions.
+
+## Features
+
+- Prompt management (display, editing, history)
+- Command execution (with or without arguments)
+- Basic shell operations (pipes, redirections)
+- Environment variables management (listing, setting, unsetting)
+- Built-in functions management (echo, cd, env, exit, export, pwd, unset)
+
+## Getting started
+
+1. Clone this repository: `git clone https://github.com/<your_username>/minishell.git`
+2. `cd` into the cloned directory: `cd minishell`
+3. Run the `make` command to compile the program: `make`
+4. Start the shell by running the executable: `./minishell`
+
+## Usage
+
+Once the shell is started, you can enter commands as you would with any other shell. The following are some examples of commands that can be executed:
+
+- Display the working directory: `pwd`
+- Change directory: `cd <directory_name>`
+- Print the value of an environment variable: `echo $<variable_name>`
+- Set an environment variable: `export <variable_name>=<value>`
+- Unset an environment variable: `unset <variable_name>`
+- Display a list of environment variables: `env`
+- Exit the shell: `exit`
+
+## Resources
+
+- ![The project subject](./subject.pdf)
+- The C library documentation for the standard library functions used in the program
+- bash man
+
+## Authors
+
+This project was created by [Camille CHAUVET](mailto:camille@chauvet.pro) and [Xamora](mailto:ogame.xamora@42l.fr). If you have any questions or suggestions, feel free to contact us.
