To start using Composer in your project, all you need is a composer.json file. This file describes the dependencies of your project and may contain other metadata as well.
To get help from the command-line, call composer or composer list to see the complete list of commands, then --help combined with any of those can give you more information.
Composer will correctly pick your package over the original one since the custom repository has priority over packagist. If you want to rename the package, you should do so in the default (often master) branch and not in a feature branch, since the package name is taken from the default branch.
Composer allows repositories to define a notification URL, so that they get notified whenever a package from that repository is installed. This option allows you to disable that behavior.
Packagist is the main package repository for Composer, and it is enabled by default. Anything that is published on Packagist is available automatically through Composer.
