Documentation for codex.ww.wp.xz.cn

Is the handy http://melchoyce.github.io/dashicons/ gallery page permanent? Will it be synched with changes in WordPress core?
I made a wiki redlink on http://codex.ww.wp.xz.cn/Function_Reference/add_menu_page for or http://codex.ww.wp.xz.cn/Dashicon (but it should probably be “Dashicons”).
I posted the same question as a Github issue.
