Thanx for explaining. But I am afraid it will still leave some difficulties, and leaks of understanding for me.
The manual says "unzip the rom". I think I must do it on the PC?
You say, "install on phone, and copy the files to the computer, then deodex"
Do I understand right?
I think when I deodex the files on the conputer, and then copy them back to the phone, I am awaiting lots of trouble with permissions.
Anyway ...
Meanwhile I found out, that it's maybe more clever to install Magisk, and then install the exposed framework via Magisk. I think it will not be not neccessary to deodex this way?! I hope this will work out ...
ps: I forgot to mention, that I wanted to deodex the rom only to use the Xposed Frmework, because the framework doesn't work on odexed roms with my S4. That's the only reason.
