 ## Does it work?
-Yes! Quite well, actually - on macOS, Windows, and Linux. Bear in mind that this is written entirely in JavaScript, so please adjust your expectations. The virtual machine is emulating a 1991 Macintosh Quadra 900 with a Motorola CPU, which Apple used before switching to IBM's PowerPC architecture in the late 1990s.

The virtual machine is emulating a 1991 Macintosh Quadra 900 with a Motorola CPU, which Apple used before switching to the PowerPC architecture (Apple/IBM/Motorola) in the mid 1990s.
 
 ## Should this have been a native app?
 Absolutely.
@@ -30,6 +117,14 @@ Yes, you can. Click on the "Help" button at the bottom of the running app to see
 
 No. For what it's worth, the web was quite different 30 years ago - and you wouldn't be able to open even Google. However, Internet Explorer and Netscape are installed, as is the "Web Sharing Server", if you want to play around a bit.
 
+## Should I use this for [serious application]?
+
+Probably not. This is a toy - it's not the best nor the most performant way to emulate an old Macintosh. It is, however, a quick and easy way to experience a bit of nostalgia if you're _not_ trying to do anything serious with it.
+
+## Credits
+
+Please check out the [CREDITS](CREDITS.md)! This app wouldn't be possible without the hard work of [Christian Bauer](https://www.cebix.net/) and [James Friend](https://jamesfriend.com.au/), who did everything that seems like computing magic here.
