-# clipboard.js
-
-> A modern approach to copy & cut to the clipboard. No Flash. No dependencies. Just 1kb.
-
-## Install
-
-You can get it using bower:
-
-```
-bower install clipboard --save
-```
-
-Or [download as ZIP](https://github.com/zenorocha/clipboard.js/archive/master.zip).
-
-## Usage
-
-First, you need to instantiate it using a selector. This selector corresponds to the trigger element, usually a `<button>`.
-
-```js
-new Clipboard('.btn');
-```
-
-The easiest way to copy some content to the clipboard, is to include a `data-text` attribute in your trigger element.
-
-```html
-<button class="btn" data-text="Lorem ipsum">Copy</button>
-```
-
-Another way of doing it, is to copy the content from an another element. You can do that by adding a `data-target` attribute in your trigger element. The value you include on this attribute needs to match another's element `id` attribute.
-
-```html
-<p id="foo">Lorem ipsum</p>
-<button class="btn" data-target="foo">Copy</button>
-```
-
-Additionally, you can define a `data-action` attribute to specify if you want to either `copy` or `cut` content. If you omit this attribute, `copy` will be used.
-
-```html
-<input id="foo" value="Lorem ipsum"></inpu>
-<button class="btn" data-action="cut" data-target="foo">Copy</button>
-```
-
-As you may expect, the `cut` action only works on `<input>` or `<textarea>` elements.
-
-## Browser Support
-
-This project relies on both [Select API](https://developer.mozilla.org/en-US/docs/Web/API/Selection) and [execCommand API](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand). When combined, they're supported in the following browsers.

+# Contributing guide
+
+Want to contribute to Clipboard.js? Awesome!
+There are many ways you can contribute, see below.
+
+## Opening issues
+
+Open an issue to report bugs or to propose new features.
+
+- Reporting bugs: describe the bug as clearly as you can, including steps to reproduce, what happened and what you were expecting to happen. Also include browser version, OS and other related software's (npm, Node.js, etc) versions when applicable.
+
+- Proposing features: explain the proposed feature, what it should do, why it is useful, how users should use it. Give us as much info as possible so it will be easier to discuss, access and implement the proposed feature. When you're unsure about a certain aspect of the feature, feel free to leave it open for others to discuss and find an appropriate solution.
+
+## Proposing pull requests
+
+Pull requests are very welcome. Note that if you are going to propose drastic changes, be sure to open an issue for discussion first, to make sure that your PR will be accepted before you spend effort coding it.
+
+Fork the Clipboard.js repository, clone it locally and create a branch for your proposed bug fix or new feature. Avoid working directly on the master branch.
+
+Implement your bug fix or feature, write tests to cover it and make sure all tests are passing (run a final `npm test` to make sure everything is correct). Then commit your changes, push your bug fix/feature branch to the origin (your forked repo) and open a pull request to the upstream (the repository you originally forked)'s master branch.
+
+## Documentation
+
+Documentation is extremely important and takes a fair deal of time and effort to write and keep updated. Please submit any and all improvements you can make to the repository's docs.
+
+## Known issues
+
+If you're using npm@3 you'll probably face some issues related to peerDependencies.
+https://github.com/npm/npm/issues/9204

-        <h1>Install</h1>
-
-        <p>You can get it on npm.</p>
-
-        <pre><code class="js">npm install clipboard --save</code></pre>
-
-        <p>Or bower, too.</p>
-
-        <pre><code class="js">bower install clipboard --save</code></pre>
-
-        <p>If you're not into package management, just <a href="https://github.com/zenorocha/clipboard.js/archive/master.zip">download a ZIP</a> file.</p>
-
-        <h1>Setup</h1>
-
-        <p>First, include the script located on the <code>dist</code> folder</p>
-
-        <pre><code class="html">&lt;script src="dist/clipboard.min.js"&gt;&lt;/script&gt;</code></pre>
-
-        <p>Now, you need to instantiate it using a DOM selector. This selector corresponds to the trigger element, i.e. <code>&lt;button&gt;</code>.</p>
-
-        <pre><code class="html">&lt;script&gt; new Clipboard('.btn'); &lt;/script&gt;</code></pre>
-
-        <h1>Usage</h1>
-
-        <p>We're living a <em>declarative renaissance</em>, that's why we decided to take advantage of <a href="https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes">HTML5 data attributes</a> for better usability.</p>
-
-        <h3>Copy text from attribute</h3>
-
-        <p>The easiest way to copy some content to the clipboard, is to include a <code>data-text</code> attribute in your trigger element.</p>
-
-        <div class="example">
-            <button class="btn" data-action="copy" data-text="Just because you can doesn't mean you should — clipboard.js">Copy to the clipboard</button>
-        </div>
-
-        <pre><code class="html">&lt;!-- Trigger --&gt;
-&lt;button class="btn" data-text="Heya!"&gt;Copy&lt;/button&gt;</code></pre>
-
-        <h3>Copy text from another element</h3>
-
-        <p>Alternatively, you can copy content from another element by adding a <code>data-target</code> attribute in your trigger element.</p>
-        <p>The value you include on this attribute needs to match another's element <code>id</code> attribute.</p>
-
-        <div class="example">
-            <div class="input-group">
-                <input id="foo" type="text" value="https://github.com/zenorocha/clipboard.js.git">

+
+![Build Status](https://github.com/zenorocha/clipboard.js/workflows/build/badge.svg)
+![Killing Flash](https://img.shields.io/badge/killing-flash-brightgreen.svg?style=flat)
+
+> Modern copy to clipboard. No Flash. Just 3kb gzipped.
+
+<a href="https://clipboardjs.com/"><img width="728" src="https://cloud.githubusercontent.com/assets/398893/16165747/a0f6fc46-349a-11e6-8c9b-c5fd58d9099c.png" alt="Demo"></a>
+
+## Why
+
+Copying text to the clipboard shouldn't be hard. It shouldn't require dozens of steps to configure or hundreds of KBs to load. But most of all, it shouldn't depend on Flash or any bloated framework.
+
+That's why clipboard.js exists.
+
+## Install
+
+You can get it on npm.
+
+```
+npm install clipboard --save
+```
+
+Or if you're not into package management, just [download a ZIP](https://github.com/zenorocha/clipboard.js/archive/master.zip) file.
+
+## Setup
+
+First, include the script located on the `dist` folder or load it from [a third-party CDN provider](https://github.com/zenorocha/clipboard.js/wiki/CDN-Providers).
+
+```html
+<script src="dist/clipboard.min.js"></script>
+```
+
+Now, you need to instantiate it by [passing a DOM selector](https://github.com/zenorocha/clipboard.js/blob/master/demo/constructor-selector.html#L18), [HTML element](https://github.com/zenorocha/clipboard.js/blob/master/demo/constructor-node.html#L16-L17), or [list of HTML elements](https://github.com/zenorocha/clipboard.js/blob/master/demo/constructor-nodelist.html#L18-L19).
+
+```js
+new ClipboardJS('.btn');
+```
+
+Internally, we need to fetch all elements that matches with your selector and attach event listeners for each one. But guess what? If you have hundreds of matches, this operation can consume a lot of memory.
+
+For this reason we use [event delegation](https://stackoverflow.com/questions/1687296/what-is-dom-event-delegation) which replaces multiple event listeners with just a single listener. After all, [#perfmatters](https://twitter.com/hashtag/perfmatters).
+
+# Usage
+
+We're living a _declarative renaissance_, that's why we decided to take advantage of [HTML5 data attributes](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes) for better usability.
+
+### Copy text from another element
+
+A pretty common use case is to copy content from another element. You can do that by adding a `data-clipboard-target` attribute in your trigger element.
+
+The value you include on this attribute needs to match another's element selector.
+
+<a href="https://clipboardjs.com/#example-target"><img width="473" alt="example-2" src="https://cloud.githubusercontent.com/assets/398893/9983467/a4946aaa-5fb1-11e5-9780-f09fcd7ca6c8.png"></a>
+
+```html
+<!-- Target -->
+<input id="foo" value="https://github.com/zenorocha/clipboard.js.git" />
+
+<!-- Trigger -->
+<button class="btn" data-clipboard-target="#foo">
+  <img src="assets/clippy.svg" alt="Copy to clipboard" />
+</button>
+```
+
+### Cut text from another element
+
+Additionally, you can define a `data-clipboard-action` attribute to specify if you want to either `copy` or `cut` content.
+
+If you omit this attribute, `copy` will be used by default.
+
+<a href="https://clipboardjs.com/#example-action"><img width="473" alt="example-3" src="https://cloud.githubusercontent.com/assets/398893/10000358/7df57b9c-6050-11e5-9cd1-fbc51d2fd0a7.png"></a>
+
+```html
+<!-- Target -->
+<textarea id="bar">Mussum ipsum cacilds...</textarea>
+
+<!-- Trigger -->
+<button class="btn" data-clipboard-action="cut" data-clipboard-target="#bar">
+  Cut to clipboard
+</button>
+```
+
+As you may expect, the `cut` action only works on `<input>` or `<textarea>` elements.
+
+### Copy text from attribute
+
+Truth is, you don't even need another element to copy its content from. You can just include a `data-clipboard-text` attribute in your trigger element.
+
+<a href="https://clipboardjs.com/#example-text"><img width="147" alt="example-1" src="https://cloud.githubusercontent.com/assets/398893/10000347/6e16cf8c-6050-11e5-9883-1c5681f9ec45.png"></a>
+
+```html
+<!-- Trigger -->
+<button
+  class="btn"
+  data-clipboard-text="Just because you can doesn't mean you should — clipboard.js"
+>
+  Copy to clipboard
+</button>
+```
+
+## Events
+
+There are cases where you'd like to show some user feedback or capture what has been selected after a copy/cut operation.
+
+That's why we fire custom events such as `success` and `error` for you to listen and implement your custom logic.
+
+```js
+var clipboard = new ClipboardJS('.btn');
+
+clipboard.on('success', function (e) {
+  console.info('Action:', e.action);
+  console.info('Text:', e.text);
+  console.info('Trigger:', e.trigger);
+
+  e.clearSelection();
+});
+
+clipboard.on('error', function (e) {
+  console.error('Action:', e.action);
+  console.error('Trigger:', e.trigger);
+});
+```
+
+For a live demonstration, go to this [site](https://clipboardjs.com/) and open your console.
+
+## Tooltips
+
+Each application has different design needs, that's why clipboard.js does not include any CSS or built-in tooltip solution.
+
+The tooltips you see on the [demo site](https://clipboardjs.com/) were built using [GitHub's Primer](https://primer.style/css/components/tooltips). You may want to check that out if you're looking for a similar look and feel.
+
+## Advanced Options
+
+If you don't want to modify your HTML, there's a pretty handy imperative API for you to use. All you need to do is declare a function, do your thing, and return a value.
+
+For instance, if you want to dynamically set a `target`, you'll need to return a Node.
+
+```js
+new ClipboardJS('.btn', {
+  target: function (trigger) {
+    return trigger.nextElementSibling;
+  },
+});
+```
+
+If you want to dynamically set a `text`, you'll return a String.
+
+```js
+new ClipboardJS('.btn', {
+  text: function (trigger) {
+    return trigger.getAttribute('aria-label');
+  },
+});
+```
+
+For use in Bootstrap Modals or with any other library that changes the focus you'll want to set the focused element as the `container` value.
+
+```js
+new ClipboardJS('.btn', {
+  container: document.getElementById('modal'),
+});
+```
+
+Also, if you are working with single page apps, you may want to manage the lifecycle of the DOM more precisely. Here's how you clean up the events and objects that we create.
+
+```js
+var clipboard = new ClipboardJS('.btn');
+clipboard.destroy();
+```
+
+## Browser Support
+
+This library relies on both [Selection](https://developer.mozilla.org/en-US/docs/Web/API/Selection) and [execCommand](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand) APIs. The first one is [supported by all browsers](https://caniuse.com/#search=selection) while the second one is supported in the following browsers.

+
+The good news is that clipboard.js gracefully degrades if you need to support older browsers. All you have to do is show a tooltip saying `Copied!` when `success` event is called and `Press Ctrl+C to copy` when `error` event is called because the text is already selected.
+
+You can also check if clipboard.js is supported or not by running `ClipboardJS.isSupported()`, that way you can hide copy/cut buttons from the UI.
+
+## Bonus
+
+A browser extension that adds a "copy to clipboard" button to every code block on _GitHub, MDN, Gist, StackOverflow, StackExchange, npm, and even Medium._
+
+Install for [Chrome](https://chrome.google.com/webstore/detail/codecopy/fkbfebkcoelajmhanocgppanfoojcdmg) and [Firefox](https://addons.mozilla.org/en-US/firefox/addon/codecopy/).
