-Network configuration is simple and easy to follow:
-
-1. Choose the interface. If it's a wireless interface, you'll be prompted to select an access point (AP) and enter its password. Leave empty for open network.
-
-2. Choose between DHCP (Dynamic Host Configuration Protocol) or static IP configuration. 
-
-- If you select DHCP, the setup is complete. Optionally, you can change the MAC address.
-
-3. If you choose a static configuration, you'll need to provide:
-
-- An optional MAC address change
-- A fixed IP address (e.g., x.x.x.x/y)
-- A route (default: 0.0.0.0/0)
-- A gateway (usually x.x.x.1/24)
-- DNS (default: 9.9.9.9)
-
+1. **Select Interface:**
+   - Launch the `armbian-config` utility:
+     ```bash
+     sudo armbian-config
+     ```
+   - Navigate to `Network` and choose the desired network interface (e.g., `eth0` for wired or `wlan0` for wireless).
+
+2. **Wireless Interface Configuration:**
+   - If configuring a wireless interface:
+     - A list of available Access Points (APs) will be displayed.
+     - Select your preferred AP and enter the password when prompted. Leave the password field empty for open networks.
+
+3. **IP Address Configuration:**
+   - Choose between:
+     - **DHCP (Dynamic Host Configuration Protocol):** Automatically assigns an IP address.
+     - **Static IP:** Manually enter details:
+       - **MAC Address (optional):** Specify if you want spoofing MAC address.
+       - **IP Address:** Use CIDR notation (e.g., `192.168.1.10/24`).
+       - **Route:** Default is `0.0.0.0/0`.
+       - **Gateway:** Typically the router's IP, e.g., `192.168.1.1`.
+       - **DNS:** Default is `9.9.9.9`, but can be changed.
+
+4. **Finalize Configuration:**
+   - Review and confirm your settings.
+   - The system applies the configurations, and your network should be set up.

+## Kernel Switching Warning
+
+Switching between different kernel versions can significantly impact the functionality of your device. A newer or older kernel may introduce changes to hardware compatibility, drivers, and system stability. Some features may stop working, while others may improve or be reintroduced.  
+
+### ⚠️ Important Warning: Kernel changes carry inherent risks!  
+- A mismatched or incompatible kernel may result in **boot failures**, rendering the system unresponsive.  
+- Certain peripherals or hardware components (e.g., Wi-Fi, GPU acceleration, or power management) may no longer function correctly.  
+- Custom configurations or third-party modules might need to be recompiled or adjusted to work with the new kernel.  
+
+### ✅ Precautions Before Switching Kernels  
+Before switching kernels, it is **strongly recommended** to:  
+1. **Back up your system** to prevent data loss.  
+2. **Verify compatibility** of your hardware and essential drivers with the target kernel version.  
+3. **Keep a rescue method available**, such as a bootable SD card / USB drive or serial console access, to recover the system if necessary.  
+
+### 🛠️ Recovery Steps if Boot Fails  
+If your device fails to boot after a kernel change, you may need to:  
+- **Revert to a previous working kernel** using recovery options.  
+- **Use a serial console or debug mode** to diagnose the issue.  
+- **Reinstall the system** if no recovery options are available.  
+
+**⚡ Exercise caution when switching kernels, especially on production systems or devices with limited recovery options.**

+# 📌 ZFS (Zettabyte File System)  
+
+## 🔍 Overview  
+
+**ZFS (Zettabyte File System)** is a high-performance, scalable, and robust file system designed to provide advanced data protection, integrity, and storage management. Developed by Sun Microsystems, ZFS is widely used in enterprise environments, NAS systems, and personal storage solutions due to its unique features.  
+
+## 🛠️ Key Features  
+
+### ✅ Data Integrity  
+- **Copy-on-Write (CoW):** Prevents data corruption by never overwriting live data.  
+- **Checksumming:** Detects and corrects silent data corruption (bit rot).  
+
+### 📦 Storage Management  
+- **Pooled Storage:** Eliminates the need for traditional partitions; all storage is managed dynamically.  
+- **Snapshots & Clones:** Creates instant backups without using extra storage.  
+
+### 🚀 Performance & Scalability  
+- **Efficient Compression & Deduplication:** Reduces storage usage without performance loss.  
+- **Dynamic Striping & Caching:** Distributes data across multiple disks for optimized read/write speeds.  
+
+### 🔐 Advanced Security  
+- **Native Encryption:** Supports dataset-level encryption for secure data storage.  
+- **RAID-Z:** A superior RAID alternative that prevents write-hole issues.
