 If you need to use an HTTP proxy you can [set these environment variables](https://github.com/request/request/tree/f0c4ec061141051988d1216c24936ad2e7d5c45d#controlling-proxy-behaviour-using-environment-variables)
 
+If you want to change the architecture that is downloaded (e.g., `ia32` on an `x64` machine), you can use the `--arch` flag with npm install or set the `npm_config_arch` environment variable:
+```
+npm install --arch=ia32 electron-prebuilt
+```
