ATL720 here's a way to get started:

- find the point of maximum runout (left or right deflection from some imagined wheel centerline)
- pick the group of four spokes that are on either side of that
- Trace the four spokes back to their respective hub flange. Two will be left, two will be right
- take the two spokes that are needed to "pull" the rim back into line.
- if the rim is deflected to the left, you will tighten the 2 spokes going to the right flange
- Tighten those spokes - start with 1/4 turn
- Loosen the other two spokes going to the opposite flange by the same amount
- keep going around, working a little bit at a time, until you approach a level of true-ness that you are happy with.

you can use the bike's brakes as a reference if you don't have a truing stand. The Park spoke wrench is fine for beginners.

practice practice practice and you will build your skills.

good luck with it
