 Quickbundle allows you to bundle a library in a **quick**, **fast** and **easy** way:
 
 - Fast build and watch mode powered by Rollup[^1] and SWC[^2].
-- Compile mode to create standalone binaries for systems that do not have Node.js installed[^3].
+- Compile mode to compile and cross compile standalone binaries for systems that do not have Node.js installed[^3].
 - Zero configuration: define the build artifacts in your `package.json`, and you're all set!
 - Support of `cjs` & `esm` module formats output.
 - Support of several loaders including JavaScript, TypeScript, JSX, JSON, and Images.

 Enabling source map generation is needed only if a build is [obfuscated (minified)](#optimize-the-build-output) for debugging-easing purposes. It generally pairs with the [`minification` flag](#optimize-the-build-output).
 
+### Cross compilation to other platforms
+
+By default, the `compile` command embeds the runtime at the origin of its execution which means it generates executables compatible only with machines running the same operating system and processor architecture.
+
+However, Quickbundle provides the ability to target a different operating system or processor architecture (also known as cross compilation):
+
+```bash
+quickbundle compile --runtime node-v23.1.0-darwin-arm64 # Embeds Node v23 runtime built for macOS ARM64 target
+quickbundle compile --runtime node-v23.1.0-darwin-x64 # Embeds Node v23 runtime built for macOS X64 target
+quickbundle compile --runtime node-v23.1.0-linux-arm64 # Embeds Node v23 runtime built for Linux ARM64 target
+quickbundle compile --runtime node-v23.1.0-linux-x64 # Embeds Node v23 runtime built for Linux X64 target
+quickbundle compile --runtime node-v23.1.0-win-arm64 # Embeds Node v23 runtime built for Windows ARM64 target
+quickbundle compile --runtime node-v23.1.0-win-x64 # Embeds Node v23 runtime built for Windows X64 target
+```
+
+> [!note]
+> The accepted runtime input are the one listed in [https://nodejs.org/download/release/vx.y.z](https://nodejs.org/download/release/latest/) with the following format `node-vx.y.z-(darwin|linux|win)-(arm64|x64|x86)`.
