I did exactly as this guide describes. I downloaded the last Clover release, i.e. the Clover_v2.3k_r3899.pkg, installed the package, copied FakeSMC.kext, as well as NullCPUPowerManagement.kext and RealtekRTL8111.kext, into the /EFI/CLOVER/kext/Other/ folder, then I "copied" the "Install Sierra macOS" I had previously downloaded, by within the 10.8.5 install, in the El Capitan Application folder ("About this Mac" shows MacPro Mid 2010, and Sierra was offered for downloading). Eventually I opened Apple Store and choose to install "Sierra". The process immediately started.
1. Step 4 did not apply to me. In my system I have, other than "El Capitan", Windows 10, Mountain Lion, and Snow Leopard, in separate HD; Sierra installer offered only the choice of "El Capitan" system disk (obviously).
2. I made the choice, and in a couple of minutes the system rebooted;
3. At Clover Boot Menu I did not have the time to press the space bar for entering options; the system went in panic state and rebooted; this second time I paid more attention, and pressed the right/left arrows to move among the options; then I choose the Install Mac OS option, pressed the space bar, and a list of options appeared. None of these was Without Caches, or similar, nor Inject Kexts was present as well (I presume the procedure described by the Administrator refers to a different Clover release). I tried to write "-t" and "-T", but did not find the possibility of writing myself, as I did with the previous Clover release. So I choose "safe" ("-x") and "verbose" ("-v"). Then I started the boot, and the system kept on tracing strings on the screen for more than 15 minutes. Then I reset and turned off the system (to avoid unreversible damages), reverting to the fully working "El Capitan" 10.11.2, wandering if it would be better, and safe, for me to try to update to 10.11.6, or not.
Could anyone improve my understanding and tell me if and where I'm wrong, or could the Administrator upgrade the procedure referring to the last release of Clover?
Thank you all.

What works in El Capitan 10.11.2 (installed on October 31, 2016, TonyMac Unibeast-Multibeast)
Everything:
Full resolution HD --> DVI Graphics,
Ethernet RTL 8111,
Audio (3 in 1 External via line-out, didn't test Audio through Hdmi yet);
Usb Philips WebCam;
Resume after sleep.
The El Capitan installation looks the fastest among all the other OS's I have installed in my old bios system (Windows 10 Anniversary Edition, Mountain Lion 10.8.5, Snow Leopard 10.6.8).
What does not work:
Sometime the system takes a long time for shutting down. The Reboot is always "normal".
