1. Install Nix
   Debian

   Bash

   $ apt install --yes curl git jq nix

   Ubuntu

   Bash

   $ apt install --yes curl git jq nix

   Arch

   Bash

   $ pacman --sync --refresh --noconfirm curl git jq nix

2. Download a configuration file

   # default.nix
   {
     ngipkgs ? import (fetchTarball "https://github.com/ngi-nix/ngipkgs/tarball/main") { },
   }:
   ngipkgs.demo-vm (
     {
       pkgs,
       ...
     }:
   
     {
       # install tools (N4L, searchN4L, ...)
       programs.sstorytime.enable = true;
   
       services.sstorytime = {
         enable = true;
         port = 3030;
         openFirewall = true;
         createLocalDatabase = true;
       };
     }
   )

3. Enable binary substituters

   Bash

   $ export NIX_CONFIG='substituters = https://cache.nixos.org/ https://ngi.cachix.org/
   trusted-public-keys = cache.nixos.org-1:6nchdd59x431o0gwypbmraurkbj16zpmqfgspcdshjy= ngi.cachix.org-1:n+cal72roc3qqulxihpv+tw5t42whxmmhpragkrsrow='

4. Build and run a virtual machine
   Debian Sid/Trixie

   Bash

   $ nix-build ./default.nix && ./result

   Ubuntu 25.04

   Bash

   $ nix-build ./default.nix && ./result

   Ubuntu 24.04

   Bash

   $ rev=$(nix-instantiate --eval --attr sources.nixpkgs.rev https://github.com/ngi-nix/ngipkgs/archive/master.tar.gz | jq --raw-output)

   $ nix-shell -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/$rev.tar.gz --packages nix --run "nix-build ./default.nix && ./result"

   Arch

   Bash

   $ nix-build ./default.nix && ./result

5. Usage Instructions

   1. Download an n4l example file from the SSTorytime repository, like SSTorytime.n4l, and ingest it with the following command:

      $ wget https://raw.githubusercontent.com/markburgess/SSTorytime/refs/heads/main/examples/SSTorytime.n4l
      $ N4L -u SSTorytime.n4l
      

      This will transform the file to a graph and upload it to the database.

   2. Search for a term in the graph with the command line:

      searchN4L -v SSTorytime
      

   3. Or visit http://127.0.0.1:3030 in your browser for a visual search

   4. Check out the documentation for more usage examples.

{
  programs.sstorytime.enable = true;
}

{
  pkgs,
  ...
}:

{
  services.sstorytime = {
    enable = true;
    port = 3030;
    openFirewall = true;
    createLocalDatabase = true;
  };
}
