-Quickest start
-==============
-
-First, let's enable the Gentoo Haskell overlay using the eselect-repository method::
-
-    # Install eselect-repository if you don't already have it
-    emerge app-eselect/eselect-repository
-    # Fetch and output the list of overlays
-    eselect repository list
-    eselect repository enable haskell
-
-Finally, we need to unmask the overlay (this does not apply if your system
-is already running on the ~testing branch)::
-    # Unmask ~testing versions for your arch:
-    echo "*/*::haskell" >> /etc/portage/package.accept_keywords
+Quick start
+===========
 
-And here is the trick to speed up metadata resolution a bit.
-If you happen to use ``eix-sync`` for rsyncs you might
-like the following ``/etc/eix-sync.conf``::
+Enable the ``haskell`` overlay in the normal manner explained here::
 
-    *
-    @egencache --jobs="$(($(nproc) + 1))" --repo=haskell --update --update-use-local-desc
+https://wiki.gentoo.org/wiki/Eselect/Repository
 
-It basically means:
+Optionally, enable a sync hook to automatically generate metadata for you::
 
-- sync overlays in layman list before the main tree sync
+https://wiki.gentoo.org/wiki//etc/portage/repo.postsync.d#Pkgcore_example
 
-- generate metadata for haskell repo after main
-  tree sync is done, using N+1 cores
