Remove all the old spokes from your wheel

Spoke the 8 speed gear into the wheel. This is the best guide https://www.youtube.com/watch?v=mIU6mi0K...

Tighten all the spokes using a screwdriver. Use the same torque on the screwdriver and check by "plucking" the spokes so they sound the same

Turn the bike upside down, install the wheel, and true the wheel. I hold a screwdriver against the frame and slowly spin the wheel. When it moves in, I just tighten the opposite spokes
