I'm also Confused. Having had a quick look at the map, even though I don't know the hill at all, the directions make perfect sense and the route obvious. I'm guessing you're unfamiliar with navigating, apologies if not, and nothing to be ashamed of.

Maps open your eyes to the potential adventures all around you, and are a key tool to then carrying them out. The Ordnance Survey website has some good starting points, their Guides section having some good "how to" stuff:
