First of all, you must have a custom recovery installed and a full ROM backup before doing this process. (just incase you'll experience bootloop-you can easily restore your system)
1. Download SuperSU.zip that is compatible with your device.
2. After downloading, boot to recovery (custom recovery like twrp).
3. Click install and locate the downloaded SuperSU.zip. Click it and swipe to flash.
4. Wait for few minutes until flashing is finished.
5. Wipe cache/dalvik cache and reboot phone.
6. Congratulations! Your android smartphone is now rooted.
