7. Complete Installation: Review your settings and click “Install” to begin the installation process. Once complete, restart your computer and remove the USB drive.

Configuration

Basic Configuration

After installation, there are several configuration tasks you should perform:

1. Update Your System: Open a terminal and run the following commands to update your system:

   sudo pacman -Syu

2. Install Essential Software: Use the package manager to install essential software packages:

   sudo pacman -S vim git docker

3. Enable Docker: If you plan to use Docker, enable and start the Docker service:

   sudo systemctl enable docker
   sudo systemctl start docker

Advanced Configuration

For advanced users, consider the following configuration options:

• Custom Kernel: Install a custom kernel for specific hardware needs or performance improvements.
• Security Enhancements: Implement security measures such as firewalls, SELinux, or AppArmor.
• System Optimization: Fine-tune system settings for optimal performance using tools like sysctl and systemd configurations.

Usage and Performance

Manjaro excels in both usability and performance. Here are some real-world examples of how it can be utilized:

Development Environment

Set up a full-fledged development environment:

sudo pacman -S code python nodejs

With these tools, you can develop applications, manage version control with Git, and deploy containerized applications using Docker.

File Server

Transform your Manjaro system into a file server:

sudo pacman -S samba
sudo nano /etc/samba/smb.conf

Configure Samba by editing the smb.conf file to share directories across your network.

Comparison/Alternative Options

Advantages & Disadvantages

Advantages

• Highly customizable and flexible.
• Excellent hardware support out-of-the-box.
• Regular updates with the rolling release model.

Disadvantages
