If you face issues like poor RAM management or storage issues, you have not followed the instructions and/or have changed kernel/recovery. STRICTLY follow the instructions provided again before reporting any issues.
Formatting with PixelOS Recovery (yes, I mean PixelOS Recovery ONLY) is MUST during clean flash

Clean Flash (coming from a different ROM)

Clean flash involves formatting data which means you will be loosing data stored in the internal storage of your device, data in SD Card should not be affected. I will not be responsible for any loss of data.

Download ROM, recovery and super_empty files to your computer (click on recovery button for recovery and super_empty)
Reboot the device to bootloader (Fastboot Mode)
Flash empty super image by running fastboot wipe-super <path/to/super_empty.img> in terminal
Flash recovery image by running fastboot flash recovery <path/to/recovery.img> in terminal
Reboot to recovery mode
Go to main menu > Factory reset > Format data/factory reset > Format data - Back to Main menu
On your phone [which is in recovery mode], Apply update > Apply from ADB
Flash the ROM through ADB sideload by running adb sideload <path/to/rom.zip> in terminal
Reboot and voila!

Dirty Flash / Update

There will be no loss of data if everything goes well. Keep backups incase of any mishap. I will not be responsible for any loss of data.

Download ROM file to your computer
Reboot the device to recovery
On your phone [which is in recovery mode], Apply update > Apply from ADB
Flash the ROM through ADB sideload by running adb sideload <path/to/rom.zip> in terminal
Reboot and voila!

Notes

If you get the following error: fastboot: usage: unknown command wipe-super, make sure ADB and fastboot are updated to the latest version. You need fastboot version 28.0.2 or greater.
If installation fails with the following error: [liblp]Logical partition metadata has invalid geometry magic signature., make sure you did the previous step properly, and repeat it if needed
