Tutorials are scarce

But there's one I know of.
Go to YouTube and search. As far as I know there's just one tutorial.
However, it is mostly intuitive. Maybe if I briefly told you the steps you'd grasp the idea straight away. Which is what I did. In fact I used the method before I found out it existed.
First two blocks. As per normal really.
Corners. Go search up some vandenbergh corner algs; you only need one, and it can be done intuitively by influencing the second block anyway.
LSE- this is tricky. LR edges are done with M2; (1,0)/(-1,-1)/(0,1).
And also find an alg to swap FU and DF, there's one from vandenbergh. Or invent one yourself.
Now, permuting the M slice. This is easily done with the same alg to swap FU and DF, and the parity alg which you can conjugate for your needs.
Hope this helps. If not, PM me then I can explain it fully. It's just annoying to type on my phone right now (computer broke) :/
Edit: for corners you can just use the T-perm that starts with R2 U R2 U' R2.
Funnily enough it works on a square-1 too.
