Only module owners may edit this page.

They may:

  • update any information about their module except the name of the owner
  • add or remove sub-modules
  • change the owner of a sub-module
  • add emeritus owners or peers

Other changes, including changes of module owner or addition/removal of modules, must be agreed with the Module Ownership Module group, probably via a discussion in mozilla.governance.
