Could someone give me some very basic examples and some explanations of what enums do?

I'm following a tutorial but it's not really explained them before use, and the MSDN page is a little over complexing it.

It is a way to store multiple items in sequential order, each with its own numeric index. An example:

enum Rating {Poor, Average, Okay, Good, Excellent}

Rating IncrementRating(Rating r)
{
    if(r == Rating.Excellent)
        return r;
    else
        return r+1;
}
Rating DecrementRating(Rating r)
{
    if(r == Rating.Poor)
        return r;
    else
        return r-1;
}

As you can see there is a good use in this, for example defining error codes or messages, as you can compare them as integers by name. Some more examples can be found here:
