I made a little documentation where I explain how you can get started with Digital Logic Sim V2!

Development is very difficult at the moment because of exams

When you save a chip, click on customize (next to save) and you can add the displays and change the size and colour of the chip.

I'm now pretty much done with all exams so I'll continue the development in the next few days.
