-
-## Options
-
-You can customize the Keyboard by passing options (props) to it.
-Here are the available options (the code examples are the defaults):
-
-### layout
-
-> Modify the keyboard layout
-
-```js
-layout={{
-  'default': [
-    '` 1 2 3 4 5 6 7 8 9 0 - = {bksp}',
-    '{tab} q w e r t y u i o p [ ] \\',
-    '{lock} a s d f g h j k l ; \' {enter}',
-    '{shift} z x c v b n m , . / {shift}',
-    '.com @ {space}'
-  ],
-  'shift': [
-    '~ ! @ # $ % ^ & * ( ) _ + {bksp}',
-    '{tab} Q W E R T Y U I O P { } |',
-    '{lock} A S D F G H J K L : " {enter}',
-    '{shift} Z X C V B N M < > ? {shift}',
-    '.com @ {space}'
-  ]
-}}
-```
-
-### layoutName
-
-> Specifies which layout should be used.
-
-```js
-layoutName={"default"}
-```
-
-### display
-
-> Replaces variable buttons (such as `{bksp}`) with a human-friendly name (e.g.: "delete").
-
-```js
-display={{
-  '{bksp}': 'delete',
-  '{enter}': '< enter',
-  '{shift}': 'shift',
-  '{s}': 'shift',
-  '{tab}': 'tab',
-  '{lock}': 'caps',
-  '{accept}': 'Submit',
-  '{space}': ' ',
-  '{//}': ' '
-}}
-```
-
-### theme
-
-> A prop to add your own css classes. You can add multiple classes separated by a space.
-
-```js
-theme={"hg-theme-default"}
-```
-
-### debug
-
-> Runs a console.log every time a key is pressed. Displays the buttons pressed and the current input.
-
-```js
-debug={false}
-```
-
-### newLineOnEnter
-
-> Specifies whether clicking the "ENTER" button will input a newline (`\n`) or not.
-
-```js
-newLineOnEnter={true}
-```
-
-## Methods
-
-simple-keybord has a few methods you can use to further control it's behavior.
-To access these functions, you need a `ref` of the simple-keyboard component, like so:
-
-```js
-<Keyboard
-  ref={r => this.keyboard = r}
-  [...]
-/>
-
-// Then, on componentDidMount ..
-this.keyboard.methodName(params);
-```
-
-### clearInput
-
-> Clear the keyboard's input.
-
-```js
-this.keyboard.clearInput();
-```
-
-### getInput
-
-> Get the keyboard's input (You can also get it from the _onChange_ prop).
-
-```js
-let input = this.keyboard.getInput();
-```
-
-### setInput
-
-> Set the keyboard's input. Useful if you want the keybord to initialize with a default value, for example.
-
-```js
-this.keyboard.setInput("Hello World!");
-```
-
-It returns a promise, so if you want to run something after it's applied, call it as so:
-
-```js
-let inputSetPromise = this.keyboard.setInput("Hello World!");
-
-inputSetPromise.then((result) => {
-  console.log("Input set");
-});
-```
-

+
+## ✳️ 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/)
+* [Key Navigation](https://franciscohodge.com/projects/simple-keyboard/demo-showcase/module-key-navigation/)
+* [Swipe Keyboard](https://franciscohodge.com/projects/simple-keyboard/demo-showcase/module-swipe-keyboard/)
+
+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).
