You should add at the top of CBHC page that CBHC replaces completely Haxchi.
a lot of people think they have both installed at the same time, and that they need to update haxchi after installing cbhc.
it can brick their consoles ! (that's why doing NAND backup is useful)
explain that it replaces haxchi (or tell it's an update of haxchi, maybe that is easier to understand? but it's not.)
Explain that they should NEVER update or reinstall haxchi if they have CBHC, it will semi-brick (should still be recoverable)
Explain that they should NEVER EVER format their WiiU if they have CBHC, it will full brick !
you don't explain that haxchi can be used as "forwarder" to launch many homebrew, without going into the HBL.
users might want to use haxchi instead of CBHC, just for that feature.
or they might want both (it's possible).
that's just multiple possibilities that straightforward guide never explain, they just "make all consoles clones of others", all hacks are often always identical, not necessarily the best (I do reference to
vWii hacking guide, telling ALL users to install wrong cIOS.... and then coming here to get help because it's not working)
