+# Nix dependencies
+
+Cardano-node nix build depends primarily on [haskell.nix](https://github.com/input-output-hk/haskell.nix) and secondarily, for some utilities, on [iohk-nix](https://github.com/input-output-hk/iohk-nix/).
+
+Both can be updated from within a cardano-node `nix-shell` with:
+
+```
+nix flake update --update-input haskellNix
+nix flake update --update-input iohkNix
+```
+
+Or from outside the `nix-shell` with the scripts:
+
+```
+./nix/update-haskellNix.sh
+./nix/update-iohkNix.sh
+```
