+      ## Prerequisites
+      - Unlocked bootloader
+      - Custom recovery (TWRP recommended)
+      - USB debugging enabled
+      - ADB and Fastboot tools installed
+      
+      ## Installation Steps
+      
+      ### Method 1: Recovery Flash (Recommended)
+      1. Download the ROM zip file from the artifacts
+      2. Boot into recovery mode
+      3. Wipe system, data, cache, and dalvik cache
+      4. Flash the ROM zip file
+      5. Flash GApps if desired
+      6. Reboot system
+      
+      ### Method 2: Fastboot Flash (Advanced)
+      1. Boot into fastboot mode
+      2. Flash individual image files:
+         ```bash
+         fastboot flash boot boot.img
+         fastboot flash system system.img
+         fastboot flash vendor vendor.img
+         fastboot flash recovery recovery.img
+         ```
+      3. Reboot system
+      
+      ## Verification
+      - Check build date in Settings > About Phone
+      - Verify ROM version matches build info
+      - Test basic functionality before daily use
+      
+      ## Support
+      - Check build logs if issues occur
+      - Verify checksums before flashing
+      - Create backup before installation
