# Governance

## Overview

To add, remove, or update module information, see the
[mots documentation](https://mots.readthedocs.io/en/latest/#adding-a-module>).

Thunderbird operates under Mozilla's [module ownership governance system](
https://www.mozilla.org/hacking/module-ownership.html). A module is a
discrete unit of code or activity. An owner is the person in charge of a
module or sub-module. A peer is a person whom the owner has appointed to
help them. A module may have multiple peers and, very occasionally, multiple
owners.

The system is overseen by the owner and peers of the Module Ownership module.
For the modules that make up Thunderbird, oversight is provided by the
Thunderbird Council module. Owners may add and remove peers from their modules
as they wish, without reference to anyone else.


## Modules

### Thunderbird Council

The Thunderbird Council is the elected governing body for the Thunderbird
Project, including the code modules that develop the code in Thunderbird
product\(s\)\. It is the top\-level module of the project, and Peers are
members of the Council\.
 To read the details about the qualifications and expectations of Council
members, please see the \[Council Bylaws on GitHub\]\(https://github\.com/thund
erbird/council\-docs/blob/main/BY\_LAWS\.md\#election\-procedure\)\.
 Below you can find a list of all current council members along with their
bugzilla\.mozilla\.org \\\(BMO\\\) handle\.
To contact the council members, please email \<council@thunderbird\.net\>\.
