This site is written by a beginner.
I have noted my experiences while I tied to discover this and that in the IT world. Basically I have taken notes while learning and then put it into a bit of form.
It is a all a bit here and there. Still, I hope that it might be helpful for other beginners to see my experiences and to have a kick-start to see how some things work. Of course there sometimes might be much better ways to do things that I have not discovered yet, but it is a start.
Have fun , Marcus.
