+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at opensource@hodgef.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-## 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}'
-  ]
-}
-```
-
-> Looking for keyboard layouts in other languages? **Check out [simple-keyboard-layouts](https://github.com/hodgef/simple-keyboard-layouts) !**
-
-### layoutName
-
-> Specifies which layout should be used.
-
-```js
-layoutName: "default"
-```
-
-### display
-
-> Replaces variable buttons (such as `{bksp}`) with a human-friendly name (e.g.: "backspace").
-
-```js
-display: {
-  '{bksp}': 'backspace',
-  '{enter}': '< enter',
-  '{shift}': 'shift',
-  ...
-}
-```
-
-### mergeDisplay
-
-By default, when you set the `display` property, you replace the default one. This setting merges them instead.
-
-```js
-mergeDisplay: true,
-
-display: {
-  '{bksp}': 'delete',
-  '{enter}': 'submit',
-}
-
-// Result:
-{
-  '{bksp}': 'delete'
-  '{enter}': 'submit',
-  '{shift}': 'shift', // < Merged from default among others
-  ....
-}
-```
-
-### 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_.
-
-To add or remove individual `buttonTheme` entries, check out the methods `addButtonTheme` and `removeButtonTheme` below.
-
-```js
-buttonTheme: [
-  {
-    class: "myCustomClass",
-    buttons: "Q W E R T Y q w e r t y"
-  },
-  {
-    class: "anotherCustomClass",
-    buttons: "Q q"
-  },
-  ...
-]
-```

-
-
-### 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
-```
-
-### tabCharOnTab
-
-> Specifies whether clicking the "TAB" button will input a tab character (`\t`) or not.
-
-```js
-tabCharOnTab: true
-```
-
-### inputName
-
-> Allows you to use a single simple-keyboard instance for several inputs.
-
-```js
-inputName: "default"
-```

-
-
-### maxLength
-
-> Restrains simple-keyboard's input to a certain length. This should be used in addition to the input element's `maxlength` attribute.
-
-```js
-// Applies to all internal inputs
-maxLength: 5
-
-// Specifies different limiters for each input set, in case you are using the "inputName" option
-maxLength: {
-  'default': 5,
-  'myFancyInput': 10
-}
-```
-
-<a href="https://codesandbox.io/s/github/hodgef/demo_npm_simple-keyboard_max-length" title="run demo" target="_blank"><img src="https://franciscohodge.com/project-pages/simple-keyboard/images/rundemo200.png" width="150" align="center"></a>
-
-
-### syncInstanceInputs
-
-> When set to true, this option synchronizes the internal input of every simple-keyboard instance.
-
-```js
-syncInstanceInputs: false
-```
-
-### physicalKeyboardHighlight
-
-Enable highlighting of keys pressed on physical keyboard.
-
-For functional keys such as `shift`, note that the key's `event.code` is used. In that instance, pressing the left key will result in the code `ShiftLeft`. Therefore, the key must be named `{shiftleft}`.
-[Click here](https://github.com/hodgef/simple-keyboard/blob/master/src/lib/services/Utilities.js#L58) for some of keys supported out of the box.
-
-If in doubt, you can also set the `debug` option to `true` to see the key events.
-
-```js
-physicalKeyboardHighlight: true
-```
-
-<a href="https://codesandbox.io/s/github/hodgef/demo_cdn_simple-keyboard_extended-full-keyboard" title="run demo" target="_blank"><img src="https://franciscohodge.com/project-pages/simple-keyboard/images/rundemo200.png" width="150" align="center"></a>
-
-### physicalKeyboardHighlightTextColor
-
-Define the text color that the physical keyboard highlighted key should have. Used when `physicalKeyboardHighlight` is set to true.
-
-```js
-physicalKeyboardHighlightTextColor: "white"
-```
-
-### physicalKeyboardHighlightBgColor
-
-Define the background color that the physical keyboard highlighted key should have. Used when `physicalKeyboardHighlight` is set to true.
-
-```js
-physicalKeyboardHighlightBgColor: "#9ab4d0"
-```
-
-### 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)
-```
-
-### onRender
-
-> Executes the callback function every time simple-keyboard is rendered (e.g: when you change layouts).
-
-```js
-onRender: () => console.log("simple-keyboard refreshed")
-```
-
-### onInit
-
-> Executes the callback function once simple-keyboard is rendered for the first time (on initialization).
-
-```js
-onInit: () => console.log("simple-keyboard initialized")
-```
-
-### 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("myInputName");
-```
-
-### 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("myInputName");
-```
-
-### 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!", "myInputName");
-```
-
-### setOptions
-
-> Set new option or modify existing ones after initialization. The changes are applied immediately.
-
-```js
-keyboard.setOptions({
-  theme: "my-custom-theme"
-});
-```
-
-### dispatch
-
-> Send a command to all simple-keyboard instances at once (if you have multiple instances).
-
-```js
-keyboard.dispatch(instance => {
-  instance.setOptions({
-    buttonTheme: [
-      {
-        class: "myClass",
-        buttons: `a b c`
-      }
-    ]
-  })
-});
-```
-
-<a href="https://codesandbox.io/s/github/hodgef/demo_npm_simple-keyboard_dispatch-method" title="run demo" target="_blank"><img src="https://franciscohodge.com/project-pages/simple-keyboard/images/rundemo200.png" width="150" align="center"></a>
-
-
-### getButtonElement
-
-> Get the DOM Element of a button. If there are several buttons with the same name, an array of the DOM Elements is returned.
-
-```js
-this.keyboard.getButtonElement('a'); // Gets the "a" key as per your layout
-this.keyboard.getButtonElement('{shift}') // Gets all keys with that name in an array
-```
-
-<a href="https://codesandbox.io/s/github/hodgef/demo_npm_simple-keyboard_get-button-element" title="run demo" target="_blank"><img src="https://franciscohodge.com/project-pages/simple-keyboard/images/rundemo200.png" width="150" align="center"></a>
-
-
-### addButtonTheme
-
-Adds an entry to the `buttonTheme`. Basically a way to add a class to a button.
-
-Unlike the `buttonTheme` property, which replaces entries, `addButtonTheme` creates entries or modifies existing ones.
-
-```js
-this.keyboard.addButtonTheme("a b c {enter}", "myClass1 myClass2");
-```
-
-### removeButtonTheme
-
-Removes an entry to the `buttonTheme`. Basically a way to remove a class previously added to a button through `buttonTheme` or `addButtonTheme`.
-
-Unlike the `buttonTheme` property, which replaces entries, `removeButtonTheme` removes entries or modifies existing ones.
-
-```js
-this.keyboard.removeButtonTheme("b c", "myClass1 myClass2");
-```
-
-## Q&A / Use-cases
-
-### How to give a different base class to my keyboard
-
-As you may have seen on the code samples, this is the default setup that simple-keyboard uses:
-
-```html
-  <div class="simple-keyboard"></div>
-```
-
-```js
-let keyboard = new Keyboard({
-  // Add options here
-});
-```
-
-You can however change this by setting up simple-keyboard like so:
-
-```html
-  <div class="myFavouriteClass"></div>
-```
-
-```js
-let keyboard = new Keyboard(".myFavouriteClass", {
-  // Add options here
-});
-```
-
-This can come in handy especially when dealing with multiple simple keyboard instances.
-
-### How to syncronize multiple instances of simple-keyboard
-
-As shown above, you can run multiple instances of simple-keyboard. To keep their internal inputs in sync, set the *[syncInstanceInputs](#syncinstanceinputs)* option to `true`.
-
-If you want to send a command to all your simple-keyboard instances at once, you can use the *[dispatch](#dispatch)* method.
-
-Here's a demo with both these features in action:
-
-
-<a href="https://codesandbox.io/s/github/hodgef/demo_npm_simple-keyboard_dispatch-method" title="run demo" target="_blank"><img src="https://franciscohodge.com/project-pages/simple-keyboard/images/rundemo200.png" width="150" align="center"></a>
-
-Here's an example of a full keyboard made out of multiple simple-keyboard instances:
-
-<a href="https://codesandbox.io/s/github/hodgef/demo_cdn_simple-keyboard_extended-full-keyboard" title="run demo" target="_blank"><img src="https://franciscohodge.com/project-pages/simple-keyboard/images/rundemo200.png" width="150" align="center"></a>
-
-### 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;
-  }
-
-```

-
-
-### Having keys in a different language configuration
-
-There's a number of key layouts available. To apply them, check out [simple-keyboard-layouts](https://github.com/hodgef/simple-keyboard-layouts).
-
-If you'd like to contribute your own layouts, please submit your pull request at the simple-keyboard-layouts repository.
-
-### How to customize my keyboard layout
-
-If you'd like to create a layout in a language not currently supported by [simple-keyboard-layouts](https://github.com/hodgef/simple-keyboard-layouts), you definitely can.
-
-Take following demo as an example:
-
-<a href="https://codesandbox.io/s/github/hodgef/demo_npm_simple-keyboard_customization" title="run demo" target="_blank"><img src="https://franciscohodge.com/project-pages/simple-keyboard/images/rundemo200.png" width="150" align="center"></a>
-
-If you have issues displaying a character, you might need its unicode code to display it. Here an useful converter tool:
-
-[r12a Unicode converter](https://r12a.github.io/app-conversion/)
-
-### Why is the caps lock button working like shift button
-
-For the sake of simplicity, caps lock and shift do the same action in the main demos.
-If you'd like to show a different layout when you press caps lock, check out the following demo:
-
-<a href="https://codesandbox.io/s/github/hodgef/demo_npm_simple-keyboard_handling-shift-caps-lock" title="run demo" target="_blank"><img src="https://franciscohodge.com/project-pages/simple-keyboard/images/rundemo200.png" width="150" align="center"></a>
-
-
-### How to display a full keyboard
-
-You can display a full keyboard by linking together multiple Simple Keyboard instances.
-This is because you might want different sections of your keyboard to have different spacing and styling.
-
-Please refer to the documentation on the *[syncInstanceInputs](#syncInstanceInputs)* option, which allows you to sync the input of all your simple-keyboard instances.
-
-Also, check out this demo:
