-## Virtual Btrfs RAID1 Setup
+[![License: GPL v3](https://img.shields.io/badge/License-GPL%20v3-blue.svg)](./LICENSE.txt) [![GitHub stars](https://img.shields.io/github/stars/kevinveenbirkenbach/linux-image-manager.svg?style=social)](https://github.com/kevinveenbirkenbach/linux-image-manager/stargazers)
 
-To setup a virtual btrfs encrypted raid 1 execute: 
+Linux Image Manager (lim) is a powerful collection of shell scripts for downloading, configuring, and managing Linux images. Whether you're setting up encrypted storage, configuring a virtual Btrfs RAID1, performing backups, or chrooting into an image, this tool makes Linux image administration simple and efficient. 🚀
+
+> **Note:** In this project, `lim` is an alias for the **main.py** wrapper script which orchestrates the execution of the various shell scripts.
+
+## Features ✨
+
+- **Image Download & Setup:** Automatically download and prepare Linux distributions.
+- **Encrypted Storage:** Configure LUKS encryption for secure image management.
+- **Virtual RAID1:** Easily set up virtual Btrfs RAID1 for data redundancy.
+- **Backup & Restore:** Create image backups from devices using dd.
+- **Chroot Environment:** Easily enter a chroot shell to maintain or modify Linux images.
+- **Automated Procedures:** Simplify partitioning, formatting, mounting, and more.
+
+## Installation 📦
+
+Install Linux Image Manager quickly using [Kevin's Package Manager](https://github.com/kevinveenbirkenbach/package-manager) under the alias `lim`. Just run:
 
 ```bash
-  bash scripts/encryption/storage/raid1/setup.sh
+package-manager install lim
 ```
 
-## Setup
+This command makes Linux Image Manager globally available as `lim` in your terminal. The `lim` alias points to the **main.py** wrapper script.
 
-To install a Linux distribution execute:
+## Usage ⚙️
 
-```bash
+The **main.py** wrapper provides a unified interface to run the different shell scripts included in this project. It supports various script types and allows you to pass additional parameters. The built-in `--help` option displays detailed usage information.
-  sudo bash ./scripts/image/setup.sh
-```
 
-## Chroot
+### Available Script Types
 
-To chroot into a Linux distribution on a storage execute:
+- **Image Setup (`--type image`):**  
+  Executes the Linux image setup located at `scripts/image/setup.sh`. This setup:
+  - Creates partitions and formats them.
+  - Transfers the Linux image file to the device.
+  - Configures boot and root partitions.
 
-```bash
+- **Single Drive Encryption Setup (`--type single`):**  
-  sudo bash ./scripts/image/chroot.sh
+  Executes the single-drive encryption setup from `scripts/encryption/storage/single_drive/setup.sh`. This setup:
-```
+  - Sets up disk encryption using LUKS on one drive.
+  - Configures a Btrfs file system for secure storage.
 
-## Backup
+- **RAID1 Encryption Setup (`--type raid1`):**  
+  Executes the RAID1 encryption setup found at `scripts/encryption/storage/raid1/setup.sh`. This setup:
+  - Configures a virtual RAID1 with two drives.
+  - Uses LUKS encryption and a Btrfs RAID1 file system for redundancy.
 
-To backup a image execute:
+- **Backup Image Setup (`--type backup`):**  
+  Executes the backup image setup located at `scripts/image/backup.sh`. This setup:
+  - Creates an image backup from a memory device to a file.
+  - Uses `dd` to transfer the image from the specified device to an image file.
 
-```bash
+- **Chroot Environment Setup (`--type chroot`):**  
-  sudo bash ./scripts/image/backup.sh
+  Executes the chroot setup from `scripts/image/chroot.sh`. This setup:
-```
+  - Mounts partitions and configures the chroot environment for a Linux image.
+  - Provides a shell within the Linux image for system maintenance.
 
-## License
+### Command-Line Options
 
-The ["GNU GENERAL PUBLIC LICENSE Version 3"](./LICENSE.txt) applies to this project.
+- **`--type`**  
+  **(Required)** Choose the type of script to execute. Options include: `image`, `single`, `raid1`, `backup`, and `chroot`.
+
+- **`--extra`**  
+  **(Optional)** Pass any extra parameters directly to the selected shell script.
+
+- **`--auto-confirm`**  
+  **(Optional)** Automatically bypass the confirmation prompt before executing the selected script.
+
+- **`--help`**  
+  **(Optional)** Displays detailed help information about the command-line options and usage of the wrapper. Simply run:
+  ```bash
+  lim --help
+  ```
+  to view the complete help message.
+
+### Example Commands
+
+- **Display Help:**  
+  ```bash
+  lim --help
+  ```
+
+- **Show Information About the Image Setup:**  
+  ```bash
+  lim --type image --info
+  ```
+
+- **Execute the Linux Image Setup (with extra parameters):**  
+  ```bash
+  lim --type image --extra --some-option value
+  ```
+
+- **Run the Single Drive Encryption Setup without a confirmation prompt:**  
+  ```bash
+  lim --type single --auto-confirm
+  ```
+
+- **Execute the RAID1 Encryption Setup:**  
+  ```bash
+  lim --type raid1
+  ```
+
+- **Perform a Backup of an Image:**  
+  ```bash
+  lim --type backup
+  ```
+
+- **Enter a Chroot Environment for a Linux Image:**  
+  ```bash
+  lim --type chroot
+  ```
+
+For additional details on each script and further configuration options, please refer to the `scripts/` and `configuration/` directories.
+
+## Configuration & Customization 🔧
+
+Customize your environment in the `configuration/` folder:
+- **General Packages:** Contains common packages for all setup scripts.
+- **Server LUKS Packages:** Contains packages needed for setting up LUKS encryption on servers.
