 ## Build Caching
 
-The builds produced by Hydra are available as a binary cache, using the cache is
-strongly recommended.
-
-The global (IPv6 only) address for the cache can be tested by fetching the
-following: http://cache.server7.hq.c3d2.de/nix-cache-info.
-
-If that fails the cache is also available within the
-[Yggdrasil](https://yggdrasil-network.github.io/) network:
-http://nix-serve.y.c3d2.de/nix-cache-info.
-
-Those with IPv6 will want to the following to their */etc/nix/nix.conf* file:
-
-```
-substituters = https://cache.nixos.org https://cache.server7.hq.c3d2.de
-trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= cache.server7.hq.c3d2.de:x8JLRG26zRZ8ysYZLEkPxuAYuK1VSJi/aMAEIs2Lv+U=
-```
-
-NixOS users may alternatively using the following configuration:
-
-```nix
-{ pkgs, ... }:
-{
-  # The following enables the use of a binary cache (IPv6 only)
-  nix.binaryCaches = [
-    "https://cache.nixos.org"
-    "https://cache.server7.hq.c3d2.de"
-    # or "http://nix-serve.y.c3d2.de"
-  ];
-  nix.binaryCachePublicKeys = [
-    "cache.server7.hq.c3d2.de:x8JLRG26zRZ8ysYZLEkPxuAYuK1VSJi/aMAEIs2Lv+U="
-  ];
-}

+A binary cache is graciously provided by Cachix, the following link provides
+instructions for enabling: https://app.cachix.org/cache/genodepkgs
