then, if you want the source, you should use [``support.source``](https://github.com/composer/composer/blob/master/res/composer-schema.json#L351) of the composer.json first in case it exists. This setting is meant to provide the url to browse the source, while ``getSourceUrl()`` is the url to clone it (github allows using the same url in both cases, but it is often not the case for other repos)
