Setting up Automapper 5.1 - asp.net-core

Question

I am having trouble following the wiki in this instance. I wanted to use Automapper 5.2. I cannot find a simple end for end example that shows a solid configuration with context. By context I mean where do you put the config files and whats the difference between static and instance api?
I checked out the DNRTV download but it deals with the 1.0 version.
How do you set this package up? I have a model called Client as below.
public class Client : IEntityBase
{
public Client()
{
Jobs = new List<Job>();
}
public int Id { get; set; }
public int ClientNo { get; set; }
public bool Company { get; set; }
public string CompanyName { get; set; }
public string ClientFirstName { get; set; }
public DateTime DeActivated { get; set; }
public bool Activity { get; set; }
public DateTime DateCreated { get; set; }
public DateTime DateUpdated { get; set; }
public int? StateId { get; set; }
public State State { get; set; }
public int CreatorId { get; set; }
public User Creator { get; set; }
public ICollection<Job> Jobs { get; set; }
}
and a ClientViewModel as so:
public class ClientViewModel
{
public int Id { get; set; }
public int ClientNo { get; set; }
public bool Company { get; set; }
public string CompanyName { get; set; }
public string ClientFirstName { get; set; }
public DateTime DeActivated { get; set; }
public bool Activity { get; set; }
public DateTime DateCreated { get; set; }
public DateTime DateUpdated { get; set; }
public int? StateId { get; set; }
public int CreatorId { get; set; }
public int[] Jobs { get; set; }
}
I am unsure how to set AutoMapper up with regard to configuration. That is, they talk about a global.asax file and I am using aspnet core.. there is no Global.asax file..
What do you put in the Startup.cs file if anything.
Given these two files above what do I need to do to use Automapper with them?

Here is the steps to configure the automapper in asp.net core mvc.
1. Create the mapping profile class which extends from Profile
public class ClientMappingProfile : Profile
{
public ClientMappingProfile ()
{
CreateMap<Client, ClientViewModel>().ReverseMap();
}
}
2. Create the AutoMapper Configuration Class and add your mapping profile class here.
public class AutoMapperConfiguration
{
public MapperConfiguration Configure()
{
var config = new MapperConfiguration(cfg =>
{
cfg.AddProfile<ClientMappingProfile>();
});
return config;
}
}
3. Create extension method so, we can add this to Startup.cs ConfigureServices method
public static class CustomMvcServiceCollectionExtensions
{
public static void AddAutoMapper(this IServiceCollection services)
{
if (services == null)
{
throw new ArgumentNullException(nameof(services));
}
var config = new AutoMapperConfiguration().Configure();
services.AddSingleton<IMapper>(sp => config.CreateMapper());
}
}
4. Call the extension method in Startup.cs ConfigureServices method
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<DBContext>(options =>options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddMvc();
services.AddAutoMapper();
}
