-## Special Mentions
+## Shoulders of Giants
 
 Without the following people, this project would never have existed:
 
   * [Dustin Krysak](https://wiki.ubuntu.com/bashfulrobot) - His support and feedback has been immense. More patience than you can throw a stick at (Not long now Dustin!).
   * [Serge Zaitsev](https://github.com/zserge) - Creator of [Webview](https://github.com/zserge/webview) which Wails uses for the windowing.
+
+And without [these people](CONTRIBUTORS.md), it wouldn't be what it is today. A huge thank you to each and every one of you!
+
+Special Mentions:
+
   * [Byron](https://github.com/bh90210) - At times, Byron has single handedly kept this project alive. Without his incredible input, we never would have got to v1.
