+You can extend simple-keyboard's functionality with [modules](https://hodgef.com/simple-keyboard/modules/). Such as:
+
+* [Autocorrect](https://hodgef.com/simple-keyboard/modules/autocorrect/)
+* [Input Mask](https://hodgef.com/simple-keyboard/modules/input-mask/)
+* [Key Navigation](https://hodgef.com/simple-keyboard/modules/key-navigation/)
+* [Swipe Keyboard](https://hodgef.com/simple-keyboard/modules/swipe-keyboard/)
+
+Want to create your own module? Check out the [Modules page](https://hodgef.com/simple-keyboard/modules/) for instructions.
+
+## Compatibility 🎯 
+
+> Simple-keyboard is intended for modern, standards-compliant browsers.
+> Internet Explorer is sadly not one of them, and since its market-share is negligible (~2% for IE11), resources won't be spent in trying to support it.
+>
