+# fish-nix-shell
+fish support for the *nix-shell* environment of the Nix package manager.
+
+## Installation
+
+### Installation in the user environment
+
+Execute
+
+```
+nix-env -if https://github.com/haslersn/fish-nix-shell/archive/master.tar.gz
+```
+
+and add the following to your *~/.config/fish/config.fish*. Create it if it doesn't exist.
+
+```
+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.
