Sure, you're supposed to download the ROM. But what does it do, exactly? Why is this site here? It's not really explained anywhere. I found a stickied thread on this forum "How is this different than miui.com?" but that was written back in 2012 and hasn't been updated. It seems the main benefit to using the new ROM is improved translation, which is something that I haven't really noticed a problem with. I've tried looking all over this site and it seems designed for people who are already experts and know what they want. I was about to post this when I saw the stickied thread, and it really didn't state a compelling case for using the new ROM.
