# Summary
All apps listed in the China Review Queue:

* approved by an app reviewer (e.g., Lisa, Andrew)
* made public
* not disabled by the user 
* not in the Escalation Queue
* marked as pending in China by the developer (see [bug 922252](https://bugzilla.mozilla.org/show_bug.cgi?id=922252))

A China Reviewer (with the `Apps:ReviewRegionCN` permission) clicks the link to "View" the app's public detail page where he/she can test/install/inspect the contents of the `.manifest`/`.zip`, etc. The Reviewer then clicks "Approve" or "Reject," which then removes the app row from the table.

This is the MVP to get Chinese apps reviewed in the Marketplace. I'm sure there are many, many more options that could be presented to the reviewers. But if there's anything crucial I'm missing let me know. (/cc @clouserw)

# TODO
* Tests
* Provide an accurate "Waiting Time" (if we determine this is something we want; /cc @clouserw)
