I found
this site helpful when installing and adjusting my R8000 front derailleur
From the website: "Whilst this article features a Shimano 105 front derailleur, the adjustment process is the same for all mechanical front derailleurs from the following Shimano group sets;
- Shimano Dura-Ace – R9100 front derailleur (FD-R9100)
- Shimano Ultegra – R8000 front derailleur (FD-R8000)
- Shimano 105 – R7000 front derailleur (FD-R7000)
- Shimano GRX – front derailleur (FD-RX810, FD-RX400)"
