This tutorial will not tell you what to do, but how things work so you figure out about what to do.
This tutorial will be a bit incomplete in some aspects (still doing research), but it gives you basic concepts and attempts to provide you some graphical awareness of what you do when you travel to other planets.
Some of the concepts shown here may also be useful for TransX MFD transfers. But explaining TransX is not the main scope of this tutorial.
Update: I added some material on how to perform slingshots with IMFD 4.2.1.
