*`dotnet restore`: Downloads the NuGet packages specified in the *.csproj* file.
*`dotnet ef migrations add Initial` Runs the Entity Framework .NET Core CLI migrations command and creates the initial migration. The parameter after "add" is a name that you assign to the migration. Here you're naming the migration "Initial" because it's the initial database migration. This operation creates the *Data/Migrations/\<date-time>_Initial.cs* file containing the migration commands to add the *Movie* table to the database.
*`dotnet ef database update` Updates the database with the migration we just created.
You'll learn about the database and connection string in the next tutorial. You'll learn about data model changes in the [Add a field](xref:tutorials/first-mvc-app/new-field) tutorial.
