hi,
I would like to learn how make a new node or a new modifier.
So I’ve tought the best way is to have a patch .diff or something like, we can read easily want we have to do in RNA, DNA,… and all the thing.
Is that possible to have? Is that a good way?

Here is the Skin Modifier commits. Read “text changed” to see the diff.
