@ -183,7 +183,7 @@ If you have the `nix` package manager installed, you can create an IHaskell
notebook environment with one command. For example:
```bash
$ nix-build -I nixpkgs=https://github.com/NixOS/nixpkgs-channels/archive/nixos-18.09.tar.gz release-8.4.nix --arg packages "haskellPackages: [ haskellPackages.lens ]"
$ nix-build -I nixpkgs=https://github.com/NixOS/nixpkgs-channels/archive/nixos-19.03.tar.gz release-8.6.nix --arg packages "haskellPackages: [ haskellPackages.lens ]"
<result path>
$ <result path>/bin/ihaskell-notebook
```

The IHaskell display modules are not loaded by default and have to be specified as additional packages:
```bash
$ nix-build -I nixpkgs=https://github.com/NixOS/nixpkgs-channels/archive/nixos-18.09.tar.gz release-8.4.nix --arg packages "haskellPackages: [ haskellPackages.ihaskell-blaze haskellPackages.ihaskell-charts ]"
$ NIXPKGS_ALLOW_BROKEN=1 nix-build -I nixpkgs=https://github.com/NixOS/nixpkgs-channels/archive/nixos-19.03.tar.gz release-8.4.nix --arg packages "haskellPackages: [ haskellPackages.ihaskell-blaze haskellPackages.ihaskell-charts ]"
```
We use GHC 8.4 here because not all dependencies have been updated to support GHC 8.6 yet.
