Shift rear cog to lowest gear (biggest cog on cassette), shift FD (Front Derailleur) to smallest ring. Dis-connect FD shift cable from FD. Loosen FD clamp and manually move FD cage to the big ring position and lower FD to proper position. Bottom of cage should be about 4mm to 5mm above big ring, make sure cage is inline with ring set while looking down at top of FD, then tighten FD clamp. Re-connect FD shift cable to FD using needle-nose pliers making sure cable is tight. (not SUPER tight, but tight). Shift rear cassette to middle cog. Then shift chain to larger ring. Shift to smallest rear cog and check for chain rub and FD cage distance from chain on big ring. Adjust if needed. Then shift rear cassette to middle cog, shift FD to small ring. Shift to largest rear cog on cassette. Check for chain rub and proper distance of FD cage from chain. Adjust if needed. Use adjustment screws on FD to position FD cage when needed. YouTube should help with most of this for instructions. You will not be able to make fine adjustments later on. You will only be able to use the screws on FD. As stated above, installing an inline barrel adjuster is easy and cheap. Ask your LBS for one, they usually have some spares laying around. You will most likely need another FD shift cable anyhow because it may too short since you are moving the FD down lower.
