How to add custom rom to rooted LG G3

I rooted my VS985 LG G3 about two years ago. Kept the stock rom. TWRP manager, Super User is installed
1. I am looking for a fast and stable rom.
2. What else do I need to do to install a custom rom.
Thanks.

Go to XDA forums and read up on custom roms. If you do ever flash a rom, you'll need to completely wipe the phone memory so don't forget to back up
