I don't understand what this challenge is asking me!

I don't know if I am just missing something blatantly obvious, so could someone show me what this question is talking about?

products/views.py 
import datetime

from django.shortcuts import render, get_object_or_404

from . import models


def good_reviews(request):
    reviews = models.Review.objects.filter(rating__gte=3)
    return render(request, 'products/reviews.html', {'reviews': reviews})


def recent_reviews(request):
    six_months_ago = datetime.datetime.today() - datetime.timedelta(days=180)
    reviews = models.Review.objects.exclude(created_at__lt=six_months_ago)
    return render(request, 'products/reviews.html', {'reviews': reviews})


def product_detail(request, pk):
    product = get_object_or_404(models.Product, pk=pk)
    reviews = product.review_set.all()
    return render(request, 'products/product_detail.html', {'product': product, 'reviews': reviews})

It is asking you to change

reviews = product.review_set.all()

so that the reviews are ordered_by the time they were '-created_at', in descending order.

Yep, use .order_by() and a '-' before created_at to get it in descending order. 

def product_detail(request, pk):
    product = get_object_or_404(models.Product, pk=pk)
    reviews = product.review_set.all().order_by('-created_at')
    return render(request, 'products/product_detail.html', {'product': product, 'reviews': reviews})

Hope that helps.
