Ninject: Entity context for the controller

I know that a thousand questions have been asked related to this topic, but I went through at least a dozen and still do not connect the dots. I am trying to configure dependency injection for entity contexts.

I always created an entity context, as I saw in MS textbooks, for example:

public class UserController : Controller
{
    private DbEntities db = new DbEntities();

}

A recent reading told me that this is no longer (if it has ever been) the best practice, and a dependency injection method should be used. Ninject is often mentioned, but I see how you go from what I have, for example, give Ninject documentation .

It should look like this when I'm done, right?

public class UserController : Controller
{
    private DbEntities db;

    public UserController(DbEntities context)
    {
        db = context;
    }
}
