+## ✳️ Modules
+
+You can extend simple-keyboard's functionality with [modules](https://franciscohodge.com/projects/simple-keyboard/modules/). Such as:
+
+* [Autocorrect](https://franciscohodge.com/projects/simple-keyboard/demo-showcase/module-autocorrect/)
+* [Input Mask](https://franciscohodge.com/projects/simple-keyboard/demo-showcase/module-input-mask/)

+
+Want to create your own module? Check out the [Modules page](https://franciscohodge.com/projects/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.
+>
+> To learn more about the rationale for not supporting IE, check out [this link](https://techcommunity.microsoft.com/t5/Windows-IT-Pro-Blog/The-perils-of-using-Internet-Explorer-as-your-default-browser/ba-p/331732).
