-# 🏁 Deno Starter
+# 🏁 Arch
 
-This is a starter template for building Deno packages in TypeScript, with GitHub Actions-powered CI, tests, CLI, and Semantic Release on GitHub and npm.
+This module is used to determine if the user is on a 32-bit vs. 64-bit operating system to offer the right app installer

-## 💡 How to use
-
-1. [Create a new repository](https://github.com/denorg/starter/generate) using this template
-2. Update the project name ("Deno Starter") from the first line in `README.md`
-3. Find and replace "denorg/starter" with your "username/repository" in `README.md`
-4. Update the "Getting started" guide with your exported functions' names
-5. In `.github/workflows/*.yml` files, add additional permissions after `deno test`
-6. Setup Semantic Release
-  - Add a repository secret `NPM_TOKEN` with your npm token
-  - In `.github/workflows/deno.yml`, find and replace "denorg/starter" with your "username/repository"
-7. Remove this section ("How to use") after setting up your respoitory
-
-If you're not building a Denorg project, the following steps are required too:
-
-1. Remove the "A project by Denorg..." footer from `README.md`
-2. Remove the "Made by Denorg" shield from the `README.md` badges section
-3. Change the "Denorg" name to yours in `LICENSE` and under "License" in `README.md`
-
 ## ⭐ Getting started
 
-Import the `mode` function and use it:
+Import the default function and use it:
 
 ```ts
-import { mode } from "https://raw.githubusercontent.com/denorg/starter/master/mod.ts";
+import arch from "https://raw.githubusercontent.com/denorg/arch/master/mod.ts";
 
-const result = mode();
+const result = await arch();
 ```
 
 ### CLI with [DPX](https://github.com/denorg/dpx)
 
 After [installing DPX](https://github.com/denorg/dpx), you can directly use the CLI using the `dpx` command:
 
 ```bash
-dpx --allow-read starter <arguments>
+dpx --allow-read arch <arguments>
 ```
 
 ### CLI
 
 Alternatively, you can use it directly from the CLI by using `deno run`:
 
 ```bash
-deno run --allow-read https://raw.githubusercontent.com/denorg/starter/master/cli.ts <arguments>
+deno run --allow-read https://raw.githubusercontent.com/denorg/arch/master/cli.ts <arguments>
 ```
 
 You can also install it globally using the following:
 
 ```bash
-deno install --allow-read -n starter https://raw.githubusercontent.com/denorg/starter/master/cli.ts
+deno install --allow-read -n arch https://raw.githubusercontent.com/denorg/arch/master/cli.ts
 ```
 
 Then, the package is available to run:
 
 ```bash
-starter <arguments>
+arch <arguments>
 ```
