 An RPN interface for the TI Nspire CX
 </p>
 
+As I really liked the rpn application for the TI-89 but could not find a usable RPN implementation for the TI nSpire, I've created rpnSpire, a powerful RPN implementation
+with many features such as searchable menus, autocompletion, an application framework in lua and many many more.
+
 ## Install
 
 Use the latest build from the *GitHub actions* and put it under `MyWidgets` on your nspire CX.
@@ -18,8 +21,6 @@ Building rpnspire depends on `luabundler` (install from `npm`) and `luna`.
 
 ## Usage
 
-Feel free to submit PRs or ask for features and fixes 😊.
