+
+> Get the operating system CPU architecture
+
+[`process.arch` / `os.arch()`](https://nodejs.org/api/process.html#processarch) is generally not useful as it returns the CPU architecture for which the Node.js binary was compiled, not the actual system architecture.
+
+For browser usage, you probably want [`is64bit`](https://github.com/sindresorhus/is64bit) instead.
+
+## Install
+
+```sh
+npm install system-architecture
+```
+
+## Usage
+
+```js
+import {systemArchitecture} from 'system-architecture';
+
+// On ARM64 macOS
+console.log(await systemArchitecture());
+//=> 'arm64'
+```
+
+## API
+
+### systemArchitecture()
+
+Returns a promise for a CPU architecture name. See [`process.arch`](https://nodejs.org/api/process.html#processarch) for possible values.
+
+### systemArchitectureSync()
+
+Returns a CPU architecture name. See [`process.arch`](https://nodejs.org/api/process.html#processarch) for possible values.
+
+## Note
+
+This should really be in Node.js core, but they are [not pragmatic](https://github.com/nodejs/node/issues/17036).
