sefou, Can I ask first if you read the ReadMe file? I included written instructions in it, about half way down.
Assuming you did, is there any thing specific that you need explained better? I’m a little hesitant to wright the same tutorial over again in pdf form if its not going to help any more than the videos.
Note: I did just resubmit the whole package as I did notice a few discrepancies in the instructions (just pending review from Unity).
