          ---
          
          ## 📥 Installation Instructions
          
          ### Prerequisites
          - Unlocked bootloader.
          - Backup your current boot image.
          - Have root access using Magisk / KernelSU / Apatch (Any forks).
          
          ### Via Kernel Flasher
          1. Download the appropriate ZIP for your device.
          2. Flash the ZIP file to active slot using Kernel Flasher.
          3. Based on root method, follow the steps:
            a. If root access is from Magisk(any forks): Perform complete uninstall from Magisk Manager.
            b. If root access is from KSU LKM(any forks): Flash Stock boot/init_boot/vendor_boot based on what you image you patched to get root access or Uninstall LKM. Recommended to flash stock image.
            c. If root access is from KSU GKI(any forks): Uninstall Manager. Delete /data/adb/ksud bin file. Reinstall Manager based on AK3 zip version. [Not required to do everytime]
            d. If root access is from Apatch(any forks): Delete all files from /data/adb. This is to start fresh and reduce multiple root implementation detected by modules.
          4. Reboot system.
          5. Install KernelSU-Next/WildSU Manager.
          6. Install SusFS module from manager.
