I landed it on Duna just now. You need an aerobrake at 12km which should give you roughly a 250km apoapsis. Then, get into a non decaying orbit. Once your orbit is stable, just burn retrograde for a few seconds with the lander section and wait for the parachutes to deploy. When they have all deployed you should be falling at around 9m/s, so just thrust gently to get your vertical velocity to about 4m/s and you'll gently touch down. I haven't tried reorbiting yet though.
