Mike,
Read and follow the instructions Troy has posted.
One little tip if you can do it - it's not terribly important but helps with collimation later on.
When doing step 4 in the procedure, if you can have the scope pointing at something distinctive (I used the front edge of the tray on a neighbour's truck) while the OTA is pointing slightly downwards, then you can bring the secondary back to pretty close to collimated after each screw is installed.
If you can't do that, then your first collimation will probably take a bit longer, that's all.
Al.
