Contributing to Wiki using GitHub

I asked this in another thread, but it may have been buried. I’ll isolate this question. (Problem with plugin integration)

RE: this tutorial:
http://www.cocos2d-x.org/wiki/Plugin-X_Integration_Guide_for_Android

I cloned the wiki GitHub repository so I could make notes and update the errors I found: https://github.com/chukong/cocos-docs

According to this doc the protocol is to clone the wiki github repo, make changes, then submit a pull request:
http://www.cocos2d-x.org/docs/README

As near as I can determine, here is the GitHub location of the doc I want to edit, however I only find the zh version not the en version:
https://github.com/chukong/cocos-docs/tree/master/manual/framework/native/wiki/plugin-x-integration-guide-for-android

Are the wiki docs on GitHub current? Where can I find the en version of the wiki entry for “plugin-x-integration-guide-for-android”?
