There is no real "right or wrong way" as such because of all the different styles that various players use.
But there is an efficient way, a way that gives the user the best chance to maximize their playing.

The video link shows and explains these points. The idea is to have as many of these elements in some form in your technique, not to try and repeat them exact. Yes there is room for adapting it for yourself so by all means do so so it fits in with what you can do. Playing techniques develop over years.
My own technique added or taking away many elements as i got older. The player i was 35 years ago is a much changed player today. The young me would struggle to understand and use the technique i have today.
