## About {% data variables.product.prodname_dotcom %} Importer

{% data variables.product.prodname_dotcom %} Importer is a tool that quickly imports source code repositories, including commits and revision history, to {% data variables.product.prodname_dotcom_the_website %} for you.

During an import, depending on the version control system you're importing from, you can authenticate with your remote repository, update commit author attribution, and either import repositories with large files or, if you don't want to use {% data variables.large_files.product_name_long %}, remove large files.

## Supported functionality by version control system
