How can I load the practice databases into Microsoft SQL Server Management Studio?

I’d like to practice within Microsoft SQL Server Management Studio. How do I import the practice database into there? I see two files: db.sqlite and population_queries

I googled how to import, and go to tasks/import data but I don’t know what type to select under data source.

Thanks much
