-# fish-nix-shell
-fish support for the *nix-shell* environment of the Nix package manager.
-
-## Installation
-
-### Installation in the user environment

-
-```
-nix-env -if https://github.com/haslersn/fish-nix-shell/archive/master.tar.gz
-```

-
-```
-fish-nix-shell --info-right | source
-```
-
-### System-wide installation
-
-Add the package to your */etc/nixos/configuration.nix*:
-
-```
-  environment.systemPackages = with pkgs; [
-    #
-    # Other packages here ...
-    #
-    (import (fetchGit "https://github.com/haslersn/fish-nix-shell"))
-  ];
-```
-
-and then execute: `sudo nixos-rebuild switch`
-
-If you want to configure it system-wide, also add:
-
-```
-  programs.fish.enable = true;
-  programs.fish.promptInit = ''
-    fish-nix-shell --info-right | source
-  '';
-```
-
-## Flags

-The `fish-nix-shell` command **optionally** takes the following flags:
-
-| Flag | Meaning |
-| - | - |
-| `--info-right` | While in a *fish-nix-shell*, display information about the loaded packages at the right.
