 # rusty-pw
-Rusty PW is a rust based generator for simple passwords
+![](/assets/Screenshot_20261024_174545.png)
+Rusty PW is a rust based generator for simple passwords. The list of words can be found at [./words.txt](./words.txt). This is a list of 200, 5 letters words that are school appropriate.
+
+> [!WARNING]
+> I do not recommend using these word-number pairs as long term security.
+> 
+> This project was built for a niche instance where I needed to make up a lot of these types of pairs.
+
+## Installation
+### macOS Apple Silicon
+1. Open a terminal and run
+```bash
+curl -fsSL https://git.briannelson.dev/brian/rusty-pw/raw/branch/main/install.sh | sh
+```
+2. Run `rusty-pw` to generate your first word-number pair
+
+### NixOS Flakes
+1. Add the flake to your inputs
+```nix
+rusty-pw = {
+  url = "git+https://git.briannelson.dev/brian/rusty-pw";
+  inputs.nixpkgs.follows = "nixpkgs";
+};
+```
+2. Add the input to your configuration as an overlay
+```nix
+{ inputs, pkgs, ... }:
+
+{
+  nixpkgs.overlays = [
+    inputs.rusty-pw.overlays.default
+  ];
+
+  environment.systemPackages = with pkgs; [ rusty-pw ];
+}
+```
+3. Rebuild your system and run `rusty-pw` to generate your first word-number pair
+
+## Options
+Here is a list of all the options available. None of these are required and a single word with 4 digits can be generated with `rusty-pw`
+| Option | Description | Default | Required |
+| --- | --- | --- | --- |
+| `--words` | Set number of words | `1` | No |
+| `--digits` | Set number of digits | `4` | No |
+| `--bulk` | Generate multiple items | `1` | No |
+| `--sep` | Seperator between words | "" | No |
+| `--save` | Export to a save file |  | No |
+| `--out` | Output file name | `rusty-pw` | No |
+
+
+## Usage
+```bash
+Random word + number generator
+
+Usage: rusty-pw [OPTIONS]
+
+Options:
+      --words <WORDS>    [default: 1]
+      --digits <DIGITS>  [default: 4]
+      --bulk <BULK>      [default: 1]
+      --sep <SEP>        [default: ""]
+      --save <SAVE>      [possible values: csv, txt]
+      --out <OUT>        [default: rusty-pw]
+  -h, --help             Print help
+  -V, --version          Print version
+```
 
 ## Features to add
-- [ ] option flag for multiple words or more numbers
+- [x] option flag for multiple words or more numbers
   - `--digits 6` or `--words 2`
-- [ ] option flag for an array of combinations for bulk generating
+- [x] option flag for an array of combinations for bulk generating
   - `--bulk 10`
-- [ ] option flag to export to .csv or .txt file
