 	This is simply going into the Entity folder and adding/modifying/deleting Properties or Classes like you would any other C# code. Note that you can't run the project with these changes before you migrate by following the next steps.
 2. Instruct EF Core to generate a Migration.
 	In the Package Manager Console or PowerShell window, move to the solution directory (which should be the default location), and run the following command:
+
 dotnet ef migrations --project TASVideos.Data --startup-project TASVideos add NameOfMigration
+
 	Name the Migration something like "AddSubmissionCycleCount" or "RemoveRatingType".
 	You should see 2 files be added with the name of your Migration, and 1 modified ModelSnapshot file.
 3. Apply the Migration.
