-## Options
-
-You can customize the Keyboard by passing options 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 _to the keyboard wrapper_. You can add multiple classes separated by a space.
-
-```js
-theme: "hg-theme-default"
-```
-
-### buttonTheme
-
-> A prop to add your own css classes _to one or several buttons_. You can add multiple classes separated by a space.
-
-```js
-buttonTheme: [
-  {
-    class: "myCustomClass",
-    buttons: "Q W E R T Y q w e r t y"
-  },
-  {
-    class: "anotherCustomClass",
-    buttons: "Q q"
-  },
-  ...
-]
-```

-[![Edit simple-keyboard customization demo - npm](https://codesandbox.io/static/img/play-codesandbox.svg)](https://codesandbox.io/s/vj8jvz2q4l?module=%2Fsrc%2Findex.js)
-
-
-### 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: false
-```
-
-### inputName
-
-> Allows you to use a single simple-keyboard instance for several inputs. 
-
-```js
-inputName: "default"
-```
-
-### onKeyPress
-
-> Executes the callback function on key press. Returns button layout name (i.e.: "{shift}").
-
-```js
-onKeyPress: (button) => console.log(button)
-```
-
-### onChange
-
-> Executes the callback function on input change. Returns the current input's string.
-
-```js
-onChange: (input) => console.log(input)
-```
-
-### onChangeAll
-
-> Executes the callback function on input change. Returns the input object with all defined inputs. This is useful if you're handling several inputs with simple-keyboard, as specified in the "*[Using several inputs](#using-several-inputs)*" guide.
-
-```js
-onChangeAll: (inputs) => console.log(inputs)
-```
-
-## Methods
-
-simple-keyboard has a few methods you can use to further control it's behavior.
-To access these functions, you need the instance the simple-keyboard component, like so:
-
-```js
-var keyboard = new Keyboard({
-  ...
-});
-/>
-
-// Then, use as follows...
-keyboard.methodName(params);
-```
-
-### clearInput
-
-> Clear the keyboard's input.
-
-```js
-// For default input (i.e. if you have only one)
-keyboard.clearInput();
-
-// For specific input
-// Must have been previously set using the "inputName" prop.
-keyboard.clearInput("inputName");
-```
-
-### getInput
-
-> Get the keyboard's input (You can also get it from the _onChange_ prop).
-
-```js
-// For default input (i.e. if you have only one)
-let input = keyboard.getInput();
-
-// For specific input
-// Must have been previously set using the "inputName" prop.
-let input = keyboard.getInput("inputName");
-```
-
-### setInput
-
-> Set the keyboard's input. Useful if you want to track input changes made outside simple-keyboard.
-
-```js
-// For default input (i.e. if you have only one)
-keyboard.setInput("Hello World!");
-
-// For specific input
-// Must have been previously set using the "inputName" prop.
-keyboard.setInput("Hello World!", "inputName");
-```
-
-### setOptions
-
-> Set new option or modify existing ones after initialization. The changes are applied immediately.
-
-```js
-keyboard.setOptions({
-  theme: "my-custom-theme"
-});
-```
-
-## Use-cases
-
-### Using several inputs
-
-Set the *[inputName](#inputname)* option for each input you want to handle with simple-keyboard.
-
-For example:
-
-```html
-  <input class="input" id="input1" value=""/>
-  <input class="input" id="input2" value=""/>
-```
-
-```js
-  // Here we'll store the input id that simple-keyboard will be using.
-  var selectedInput;
-
-  // Initialize simple-keyboard as usual
-  var keyboard = new Keyboard({
-    onChange: input => onChange(input)
-  });
-
-  // Add an event listener for the inputs to be tracked
-  document.querySelectorAll('.input')
-    .forEach(input => input.addEventListener('focus', onInputFocus));
-
-  /**
-   * When an input is focused, it will be marked as selected (selectedInput)
-   * This is so we can replace it's value on the onChange function
-   *
-   * Also, we will set the inputName option to a unique string identifying the input (id)
-   * simple-keyboard save the input in this key and report changes through onChange
-   */
-  onInputFocus = event => {
-    // Setting input as selected
-    selectedInput = `#${event.target.id}`;
-
-    // Set the inputName option on the fly !
-    keyboard.setOptions({
-      inputName: event.target.id
-    });
-  }
-
-  // When the current input is changed, this is called
-  onChange = input => {
-    // If the input is not defined, grabbing the first ".input".
-    let currentInput = selectedInput || '.input';
-
-    // Updating the selected input's value
-    document.querySelector(currentInput).value = input;
-  }
-
-```
