[Question], It this documentation abandoned?

Hello, 
yesterday I found this doc in google search (was looking for `includecode` param for R8), I couldn't find another doc with this kind of detailed info.
But also this repo its like 6 years old :(

there are plans for this documentation to be updated? or do you have know another site that's being updated with the latest info for R8 versions ?

anyway, thanks in advance.
