Start with Transfer Window Planner, select Kerbin as the origin and Duna as destination. Add your expected departure orbit from Kerbin (I usually use 100km at 0 inclination) and your target orbit over Duna (100 is the default) and then hit “plot it!”.
TWP will then make a Porkchop plot with red being bad (high delta-V cost) and blue being good, and automatically select the lowest delta-V transfer. There should be a button to add a KAC alarm for the transfer.

You should launch a little ahead of the window to make sure you don’t miss it. TWP should include the prograde, radial and normal components of the transfer burn in the alarm so you can set up your transfer burn, just remember that going away from the sun means you need to do the transfer on the dark side of Kerbin and going towards the sun means the transfer is on the day side. Use the precise controls on the node widget in the bottom left to fine-tune the timing of the burn so you get a Duna encounter; focussing the camera on Duna can be a big help for this. Alternatively, MechJeb is pretty good at doing interplanetary transfers using maneuver planner’s advanced transfer mode, which also uses a Porkchop plot to visualise it.

Re. the Porkchop plots, you can often find transfers that are a little more expensive but a lot faster than the optimal window, these can be useful if you’re using a life support mod or just want the science NOW and have fuel to spare.
