to use it just open the tool enter in your car name/make pi and go through all the boxes add in any little details you want in the user notes section . if the part is not listed ie engine swap you can type over the box with what you have even if its a drop down box
here is the hard part it does not have a save button . so to get your info in picture format just press ALT+Print Screen to screen capture , then just paste it into any paint editor program like ms paint or the apple version of it.
crop it to what you want and save and upload
