= Using Bugzilla =
Every code change starts out as a bug in bugzilla where the general approach can be discussed. The bug should eventually be assigned to somebody who will upload one or more patches for review. Code can only be reviewed by module owners and their peers. If the review has been granted and all review comments have been addressed, the patches may be submittedchecked into fx-sync.Note that other repositories such as mozilla-central may have additional procedures (e.g. you need to request approval in addition to review.)
