a new SQL learner

Hi Every one:

I am a new SQL learner and just started this week. I bought a book that comes with a downloadable database i can use to run queries and to practice my learning. I also understand that I need to install SQL Server 2016 Express and SQL Server Management Studio 2016 to my computer. Now I can't figure out how to connect to the book database from the management studio I downloaded so I can work with the database.

Thank you in advance for your input.
