Before it, please care of following tasks before you proceed with flashing custom ROM:
Task 1: Install USB drivers for your device on your PC.
Task 2: Be sure to backup your data including Contacts, SMS / MMS, APN & MMS Settings as well as photos and videos stored on your device’s internal or external storage.
Task 3: Make sure that your device is well charged. Ideally, the battery level should be around 60-80%. The more the better.
Task 4: USB Debugging should be enabled on your device.
Important: Most of the custom ROM will not have Google Apps in them. So, you will have to download and install GApps manually.

Boot your device into TWRP recovery.
Select “Wipe” from TWRP main menu and do a “Swipe to Factory Reset” on the bottom of screen.

Go back to TWRP main menu, tap on “Install” and select the Lineage os ROM .zip file and gapps for lineage os that you transferred to your device in first step.
After selecting the .zip file, do “Swipe to Confirm Flash” on the bottom of screen to begin the custom ROM installation process. This may take some time.
Once your ROM is successfully flashed, you’ll see “Wipe cache/dalvik” option, select it and then do “Swipe to wipe” on bottom of screen.
If wipe cache & dalvik is completes, hit the “Back” button on-screen and then select “Reboot System” button.
