## 🛠️ Installation Guide

### 🚀 Method 1: One-Liner (Quick Install)

#### 📌 Windows (PowerShell):

```powershell
iwr -useb https://raw.githubusercontent.com/NotHarshhaa/DevOps-Tool-Installer/main/devops.ps1 | iex
```

#### 📌 Linux (Bash):

```bash
curl -s https://raw.githubusercontent.com/NotHarshhaa/DevOps-Tool-Installer/main/devops.sh | bash
```

These **combined launchers** (`devops.ps1` and `devops.sh`) automatically guide you to install or uninstall tools via an interactive prompt!

> **Security Note**: The one-liner downloads and executes the script. For security-conscious environments, use Method 2.

---

### Method 2: Clone the Repository

#### Linux

```bash
git clone https://github.com/NotHarshhaa/DevOps-Tool-Installer.git  
cd DevOps-Tool-Installer  
chmod +x devops.sh  
./devops.sh
```

#### Windows

```powershell
git clone https://github.com/NotHarshhaa/DevOps-Tool-Installer.git  
cd DevOps-Tool-Installer  
.\devops.ps1
```

> **Security Note**: Always review scripts before execution, especially in production environments.

---

### 🔍 Method 3: Manual Download (Recommended for Security)

1. **Download the script manually:**
   - Windows: [devops.ps1](https://raw.githubusercontent.com/NotHarshhaa/DevOps-Tool-Installer/main/devops.ps1)
   - Linux: [devops.sh](https://raw.githubusercontent.com/NotHarshhaa/DevOps-Tool-Installer/main/devops.sh)

2. **Verify the script contents** (security best practice)

3. **Execute with appropriate permissions:**
   - Windows: `powershell -ExecutionPolicy Bypass -File devops.ps1`
   - Linux: `chmod +x devops.sh && sudo ./devops.sh`

---

### 🛡️ Security Requirements

- **Windows**: PowerShell 5.0+ and Administrator privileges
- **Linux**: Bash 4.0+ and root/sudo privileges
- **Network**: Internet connection for downloads and updates
