+# SSH Chroot Jail Setup Script
+
+A robust Bash script to create a chroot jail environment for SSH/SFTP users, restricting them to a specific directory on your Linux system.
+
+## 📖 Overview
+
+This script automates the process of creating a secure chroot jail environment for SSH/SFTP users, limiting their access to only specified directories. This is particularly useful for:
+
+- Web server file management
+- Secure file transfers
+- Restricting user access to specific application directories
+- Compliance with security policies
+
+## ✨ Features
+
+- Creates complete chroot jail environment
+- Sets up necessary device files and libraries
+- Configures SSHd for chroot access
+- Supports both SSH and SFTP access modes
+- Customizable jail directory location
+- Optional basic command inclusion (ls, date, mkdir)
+
+## 🛠️ Prerequisites
+
+- Linux system (tested on Ubuntu/CentOS)
+- Bash shell
+- Root/sudo access
+- SSH server installed
+
+## 📦 Installation
+
+1. Clone or download the script to your server
+2. Make the script executable:
+   ```bash
+   chmod +x create_chroot_user.sh
+   ```
+## Basic Usage
+
+
+```
+sudo ./create_chroot_user.sh
+```
+
+for the user, they have to do, and enter the password configured above
+
+```
+sftp -v user@host
+```
+
+## 🔒 Security Notes
+
+1. The jail directory and its subdirectories must be owned by root
+2. Users should not have write access to the jail structure itself
+3. Regularly update the passwd/group files in the jail if system users change
+4. Consider using key-based authentication for additional security
