+Haskell parts of the ecosystem are using [cabal2nix](https://github.com/NixOS/cabal2nix).
+Please refer to [nix documentation](https://nixos.org/nixpkgs/manual/#how-to-create-nix-builds-for-your-own-private-haskell-packages)

+Node dependencies are defined in [node-packages.json](node-packages.json).
+[Node2nix](https://github.com/svanderburg/node2nix) is used for generating nix expression

+## Binwrap Patch
+
+Some node packages might use [binwrap](https://github.com/avh4/binwrap) typically for installing
+[elmi-to-json](https://github.com/stoeffel/elmi-to-json). Binwrap is not compatible with nix.
+To overcome issues with those packages apply [patch-binwrap.nix](patch-binwrap.nix) which essentially does 2 things.
+
+1. It replaces binwrap scripts with noop shell scripts
+2. It uses nix for installing the binaries to expected location in `node_modules`
+
+Example usage be found in `elm/default.nix`.
