 * `Contents/Resources/nw.icns`: icon of your app. `nw.icns` is in [Apple Icon Image Format](https://en.wikipedia.org/wiki/Apple_Icon_Image_format). You can convert your icon in PNG/JPEG format into ICNS by using tools like [Image2Icon](http://www.img2icnsapp.com/).
 * `Contents/Info.plist`: the apple package description file. You can view [Implementing Cocoa's Standard About Panel](http://cocoadevcentral.com/articles/000071.php) on how this file will influence your app and what fields you should modify.
 
+To rename the application, the following files should be modified:
+* `Contents/Info.plist` - CFBundleDisplayName
+* `Contents/Resources/en.lproj/InfoPlist.strings` - CFBundleDisplayName
+* `package.json` -- add a string field `product_string` (e.g. foobar); the helper application will be shown as 'foobar Helper'. (since v0.24.4)
+* `Contents/Versions/n.n.n.n/nwjs Helper.app/Contents/MacOS/nwjs Helper` - rename the file to 'foobar Helper'
+* `Contents/Versions/n.n.n.n/nwjs Helper.app/Contents/Info.plist` - change CFBundleDisplayName
+* `Contents/Versions/n.n.n.n/nwjs Helper.app` - rename the directory to 'foobar Helper.app'

 You should sign your Mac app, or the user won't launch the app if Gatekeeper is turned on. See [Support for Mac App Store](Advanced/Support for Mac App Store.md) for details.
