I don't even know where to begin.

I'm confused on even where to start working on this code do I change the strings in the if / else statement to Console.WriteLine and if so where do I put the try Catch statement.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {            
            input = Console.ReadLine();

            if (input == "quit")
            {
                string output = "Goodbye.";
            }
            else
            {
                string output = "You entered " + input + ".";
            }

            Console.WriteLine(output);
        }
    }
}

They want a proper variable declareation. Variables are normaly declared at the beginning of a function.

--spoiler--

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {            
           string input = Console.ReadLine();
           string output;

            if (input == "quit")
            {
                 output = "Goodbye.";
            }
            else
            {
                 output = "You entered " + input + ".";
            }

            Console.WriteLine(output);
        }
    }
}
