[Q] MIUI V5 on Xperia Z L36H topic

Hi everyone !

Searching in the web i found this in MIUI official English website:

http://en.miui.com/download-117.html

It`s suppousedly a ported Rom of MIUI V5 for L36H... But when i looked for the installation guide i didn`t found it...
So, here are the questions:

1- Somebody knows how to install this ROM?
2- It`s working fine?
3- It`s there a MIUI V5 stable version for L36H/C6602? (all that i`ve seen was from the last year or V4)

Thanks
