If you insist on living somewhere foreign, where they do heathen things like painting taxis yellow instead of black, then you'll have to swap left-for-right and right-for-left.
When I say "left hand down", that means "turn the steering wheel anticlockwise". "Right hand down" means "turn the steering wheel clockwise", and "full lock" means "turn the steering wheel as far as you can.
Step 1: Setting up your car.
Make sure that both your wing mirrors are adjusted so that you can just see your own car in them. Adjust the rear-view mirror so that your rear window appears central to the image.
Step 2: Find your space
Park in it, man!
The ideal space is on a straight section of street, and is around a third longer than your car. With practice, you will be able to park in slightly shorter spaces without problem.
When you find your space, indicate left, slow down and drive past it. Stop about half a length past the space, with enough space between your car and the parked car for two sets of wing mirrors (about 30cm / a foot). Keep indicating left, and engage reverse gear.
