Hello,
I was reading this tutorial: How to create a language package for Magento 2?
and come here from step 3. Yet there is written ‘install extension’ not from Git repository. Would be greate if here also would be info how to install this extension without git.
Magento 2 uses Composer for the extensions management (the packages in the Composer terminology).
Packages are stored in the repositories.
Composer supports a lot of data sources for a repository (repository types in the Composer terminology): https://getcomposer.org/doc/05-repositories.md#types
