I've never had much luck navigating the wiki, but I have some suggestions for placing you page. First note that you do not automatically have a wiki account with a forum accout. But anyone can register a wiki acoount. I think I use the same username on both.
I suggest the page
https://wiki.mobileread.com/wiki/Kindle_Firmware
or
https://wiki.mobileread.com/wiki/Kin...are_Compendium
Neither of these exist, but clicking on them brings up an opportunity to create and edit it.
I would then make a link to your page at:
https://wiki.mobileread.com/wiki/Category:Kindle
There is no harm in starting with a stub, gradually expand it while experimenting with layout, restarting from scratch if necessary.
