Help with procedurally animated humanoid

So can anyone help me create a humanoid procedural animation, I know there is a tutorial on youtube by Léo Chaumartin but he skips the code, and if you download the code from its GitHub it’s the complete code not for part 2 or 3.
So can anyone help me create humanoid procedural animation for my character if someone can even give me a project file for humanoid procedural animation that would also help me a lot.
