== Release Requirements ==
Complete checklist of items that need to be satisfied before we can call this feature "done".
 
'''Waiting on Taras for definition.'''
 
== Next Steps ==
 
Waiting on a server to be set up for collection.  (Bug #[https://bugzilla.mozilla.org/show_bug.cgi?id=636217 636217])
 
* Start gathering data ASAP (simple counters).  Going to piggyback on mfinkle's addon. (Week of April 11th)
 
* Integrate chromium's histogram smarts into telemetry.  Get something ready to review to integrating into the product backend. (Week of April 18th)
 
* Set up server backend for receiving built-in telemetry.  Metrics team.  (April 18)
 
* Design & impl UI for opt-in. (???)
 
* Land it with required privacy bits. (Asa)
 
* Move on to field trials. (A/B testing)

'''Need''': Services plan, deployment plan, early items to measure.
 
== Designs ==
Any and all mockups, design specs, tech specs, etc.  Either inline or linked to.
 
== Goals/Use Cases ==


The goal for this feature is to give our developers the ability to know if changes they are making have wide-ranging positive and negative effects at scale.  Are users seeing better performance?

Another goal of this is to give us easy-to-use infrastructure to learn about the structure of the Internet as a whole.  That is, how do we tune our browser based on what the Internet and Web do?

|Feature requirements=* Modify privacy policy(Asa)
* Add UI (Mike Hommey)


== Non-Goals ==
See https://bugzilla.mozilla.org/show_bug.cgi?id=659396 for ongoing telemetry enhancements.
This is not a system for gathering feedback from individual users.  It is a system for us to get aggregate health data about browsers in the field.  It's also a chance for us to run lightweight tests if we want to learn how certain settings will affect browser performance or user experience.  It is distinct from the Test Pilot program.
