# Taskcluster Configuration
Taskcluster requires configuration of many resources to correctly support Firefox CI.
Many of those span multiple projects (branches) instead of riding the trains.
## Global Settings
The data behind configuration of all of these resources is kept in the [fxci-config] repository.
The files in this repository are intended to be self-documenting, but one of particular interest is `projects.yml`, which describes the needs of each project.
## Configuration Implementation
Translation of [fxci-config] to Taskcluster resources, and updating those resources, is handled by [ci-admin].
This is a small Python application with commands to generate the expected configuration, compare the expected to actual configuration, and apply the expected configuration.
Only the `apply` subcommand requires elevated privileges.
This tool automatically annotates all managed resources with "DO NOT EDIT", warning users of the administrative UI that changes made through the UI may be reverted.
## Changing Configuration
To change Taskcluster configuration, make patches to [fxci-config], using the Firefox Build System :: Task Configuration Bugzilla component.
The resulting configuration is applied upon landing.
