The language's autonym should be changed to "ikirundi". I see it in lots of sources, including Ethnologue and the Kirundi-English Dictionary by Elizabeth E. Cox.

The namespace names need to be added:
Media = Amasanamu, imiziki, ...
Special = Vyisangije
Talk = Ikiyago
User = Uwukoresha
User talk = Ikiyago c’uwukoresha
Wikipedia talk = Ikiyago kuri Wikipediya
File = Dosiye
File talk = Ikiyago kw’idosiye
MediaWiki = MediaWiki
MediaWiki talk = Ikiyago kuri MediaWiki
Template = Ingero
Template talk = Ikiyago cerekeye ingero
Help = Ubufasha
Help talk = Ikiyago k’ubufasha
Category = Umuce
Category talk = Ikiyago cerekeye umuce
Module = Ikigabane
Module talk = Ikiyago cerekeye ikigabane
Gadget = Gadget
Gadget talk = Ikiyago cerekeye gadget
Gadget definition = Insiguro za gadget
Gadget definition talk = Ikiyago ku nsiguro za gadget
Topic = Ishimikiro
Page = Urupapuro
Page talk = Urupapuro rw’ikiyago
Index = Ironderero
Index talk = Ikiyago kw’ironderero
Message documentation = Gushishoza ubutumwa

All of these, including the autonym, come from User:Gilbert Ndihokubwayo.
