+
+<a href="http://zenorocha.github.io/clipboard.js/"><img width="728" src="https://cloud.githubusercontent.com/assets/398893/9983535/5ab0a950-5fb4-11e5-9602-e73c0b661883.jpg" alt="Demo"></a>
+
+## Why
+
+Copy 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 using bower:
+You can get it on npm.
+
+```
+npm install clipboard --save
+```
+
+Or bower, too.
 
 ```
 bower install clipboard --save
 ```
 
-Or [download as ZIP](https://github.com/zenorocha/clipboard.js/archive/master.zip).
+If you're not into package management, just [download a ZIP](https://github.com/zenorocha/clipboard.js/archive/master.zip) file.
 
-## Usage
+## Setup
 
-First, you need to instantiate it using a selector. This selector corresponds to the trigger element, usually a `<button>`.
+First, include the script located on the `dist` folder
+
+```html
+<script src="dist/clipboard.min.js"></script>
+```
+
+Now, you need to instantiate it using a DOM selector. This selector corresponds to the trigger element(s), for example `<button class="btn">`.
 
 ```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.
+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](http://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="http://zenorocha.github.io/clipboard.js/#example-target"><img width="473" alt="example-2" src="https://cloud.githubusercontent.com/assets/398893/9983467/a4946aaa-5fb1-11e5-9780-f09fcd7ca6c8.png"></a>
 
 ```html
-<button class="btn" data-text="Lorem ipsum">Copy</button>
+<!-- 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>
 ```
 
-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.
+### 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="http://zenorocha.github.io/clipboard.js/#example-action"><img width="473" alt="example-3" src="https://cloud.githubusercontent.com/assets/398893/10000358/7df57b9c-6050-11e5-9cd1-fbc51d2fd0a7.png"></a>
 
 ```html
-<p id="foo">Lorem ipsum</p>
-<button class="btn" data-target="foo">Copy</button>
-```
+<!-- Target -->
+<textarea id="bar">Mussum ipsum cacilds...</textarea>
 
-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>
+<!-- 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="http://zenorocha.github.io/clipboard.js/#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>
+```
+
+## Advanced Usage
+
+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 Clipboard('.btn', {
+    target: function(trigger) {
+        return trigger.nextElementSibling;
+    }
+});
+```
+
+If you want to dynamically set a `text`, you'll return a String.
+
+```js
+new Clipboard('.btn', {
+    text: function(trigger) {
+        return trigger.getAttribute('aria-label');
+    }
+});
+```
+
+## 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 Clipboard('.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);
+});
+```
+

 ## 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.
+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 second one is supported in the following browsers.

 |:---:|:---:|:---:|:---:|:---:|
 | 42+ ✔ | 41+ ✔ | 9+ ✔ | 29+ ✔ | Nope ✘ |
 
+Although copy/cut operations with [execCommand](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand) aren't supported on Safari yet (including mobile), it gracefully degrades because [Selection](https://developer.mozilla.org/en-US/docs/Web/API/Selection) is supported.
+
+That means you can 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.
+
+For a live demonstration, open this [site](http://zenorocha.github.io/clipboard.js/) on Safari.

-        <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">
-                <span class="input-group-button">
-                    <button class="btn" type="button" data-action="copy" data-target="foo">
-                        <span class="octicon octicon-clippy"></span>
-                    </button>
-                </span>
-            </div>
-        </div>
-
-        <pre><code class="html">&lt;!-- Target --&gt;
-&lt;input id="foo" value="https://git.io/vn3cM"&gt;
-
-&lt;!-- Trigger --&gt;
-&lt;button class="btn" data-target="foo"&gt;Copy&lt;/button&gt;</code></pre>
-
-        <h3>Cut text from another element</h3>
-
-        <p>Additionally, you can define a <code>data-action</code> attribute to specify if you want to either <code>copy</code> or <code>cut</code> content.</p>
-        <p>If you omit this attribute, <code>copy</code> will be used by default.</p>
-
-        <div class="example">
-            <div class="input-group">
-                <textarea id="bar" cols="62" rows="4" autocomplete="off" autocorrect="off" autocapitalize="off" spellcheck="false">Mussum ipsum cacilds, vidis litro abertis. Consetis adipiscings elitis. Pra lá , depois divoltis porris, paradis. Paisis, filhis, espiritis santis. Mé faiz elementum girarzis, nisi eros vermeio, in elementis mé pra quem é amistosis quis leo. Manduma pindureta quium dia nois paga.</textarea>
-            </div>
-            <div class="form-actions">
-                <button class="btn" type="button" data-action="cut" data-target="bar">
-                    Cut to the clipboard
-                </button>
-            </div>
-        </div>
-
-        <pre><code class="html">&lt;!-- Target --&gt;
-&lt;textarea id="bar"&gt;clipboard.js rocks!&lt;/textarea&gt;
-
-&lt;!-- Trigger --&gt;
-&lt;button class="btn" data-action="cut" data-target="bar"&gt;
-    Copy
-&lt;/button&gt;</code></pre>
-
-        <p>As you may expect, the <code>cut</code> action only works on <code>&lt;input&gt;</code> or <code>&lt;textarea&gt;</code> elements.</p>
